6 Darkest Star Trek: The Next Generation Episodes, Ranked

While Star Trek is famous for its hopeful vision of the future and focus on peaceful solutions, the show also wasn’t afraid to tackle difficult and unsettling topics. Some episodes put the characters through truly challenging and disturbing experiences, and those are often the stories fans remember most.

Several episodes of the show took risks and explored more complex themes than previous installments of Star Trek. They weren’t afraid to move away from the traditional, optimistic tone and put the characters in genuinely frightening and unsettling situations, dealing with things like fear, distrust, and even losing a sense of who they were. Star Trek: The Next Generation’s writing matured and adapted to match the quality of other television shows being produced at the time. What follows are just a few examples of the series’ most intense and challenging episodes.

Chain of Command Is Picard’s Darkest Hour

Star Trek: The Next Generation wasn’t afraid to tackle difficult themes. In a two-part episode from Season 6 called “Chain of Command,” Captain Picard intentionally gives up command of the Enterprise to go on a covert mission to Celtris III, where he is captured and tortured. While he’s gone, the Enterprise is run by the strict and serious Captain Jellico.

The first part of the “Chain of Command” story arc depicts the unsuccessful mission of Captain Picard, Worf, and Dr. Crusher. They investigated what appeared to be an armory, only to discover the object of their search was sending out false signals – a trap designed to capture them. While Worf and Crusher successfully escape, the episode concludes with Picard captured and brought before Gul Madred, leaving his fate uncertain.

The story now focuses on Picard’s imprisonment and loneliness. He’s no longer the confident leader viewers know – he’s shown as genuinely weak and suffering from dehydration, hunger, and painful positions. Throughout the interrogations, Gul Madred stays composed and strategic, which makes Picard’s ordeal even more unsettling. Madred is trying to destroy Picard’s mental strength.

In the Star Trek: The Next Generation episode, a key element involves a psychological game. The character Madred repeatedly tries to convince Captain Picard that he sees five lights when only four are present. This is a deliberate attempt to undermine Picard’s resolve by forcing him to acknowledge a falsehood. The episode concludes with Picard confessing to Deanna Troi that he nearly succumbed to the pressure and admitted to seeing a fifth light, highlighting the episode’s unsettling and dark tone.

Frame of Mind Is a Psychological Horror Masterpiece

In the Star Trek: The Next Generation episode “Frame of Mind” (Season 6, Episode 21), Commander Riker, normally a strong and confident leader, finds his grip on reality shaken. Instead of facing a typical physical danger, this episode challenges Riker’s very sense of self and what he believes is real.

Okay, so the episode kicks off with Riker prepping for a play Beverly Crusher’s putting on. It quickly gets weird though – he starts to second-guess what’s real as things from the play start happening to him. Before you know it, he’s convinced he’s in an asylum! It’s this back-and-forth thing where he’ll accept one reality, then suddenly be thrown back into the other, and it’s seriously messing with his head. As the episode goes on, these reality shifts happen more and more, and Riker just gets increasingly unstable and completely lost.

The way this episode is structured deeply impacts viewers. Like Riker, we’re left wondering which reality is genuine. By focusing on Riker’s experience, the episode creates a disorienting and unsettling feeling. The episode’s theatrical elements make us question whether what we’re seeing is part of a rehearsal, and if Riker is simply immersing himself in his character.

“Frame of Mind” explores how easily even the strongest people can become vulnerable when they lose what makes them who they are. The mystery unfolds as we learn Riker was captured during a mission, taken to a medical facility, and subjected to experiments. Once he understands what happened, he regains control and sends out a distress signal.

Schisms Is One of Star Trek: The Next Generation’s Scariest Entries

Many episodes of Star Trek: The Next Generation deal with strange phenomena, but “Schisms” is particularly disturbing because of its clinical approach. It transforms the usually secure environment of the Enterprise into a site for unsettling, involuntary experiments that strip the crew of their control. Throughout the episode, various crew members are secretly taken and subjected to medical testing.

Initially, life aboard the ship seemed normal. But Commander Riker has been losing sleep and is starting to miss duties. The episode “Schisms” first shows a friendly, relaxed atmosphere on the Enterprise, with the crew enjoying a poetry reading by Data, before things begin to change. Soon, other crew members report experiencing the same sleep-related issues as Riker.

After a strange disturbance appears on the ship, the crew starts experiencing lost time – Data, Geordi, and Riker among them. As they share their experiences, they begin to realize something is wrong. Eventually, they discover an unknown alien race is abducting them while they sleep, using the disturbance as a gateway.

Dr. Crusher plays a vital role in revealing the episode’s central mystery. She provides the medical proof of the abductions and emphasizes the disturbing physical transformations happening to the crew. For example, she’s the one who tells Riker that his arm was surgically removed and then reattached. “Schisms” is particularly unsettling because it strips away the feeling of safety on the Enterprise and invades the crew’s personal space and bodies.

The Inner Light Explores Existential Questions

As a huge Star Trek fan, I always come back to “The Inner Light” from Season 5. It’s just… different. While other episodes like “Chain of Command” and “Schisms” scared me with monsters or tricky situations, this one gets under your skin in a totally new way. It’s not about being afraid of something jumping out at you, it’s about feeling sad and thoughtful about life, loss, and knowing everything eventually ends. It really makes you think about what it means to live, and it’s honestly one of the most moving episodes they’ve ever done. There’s no real ‘bad guy,’ it’s just a beautiful, heartbreaking story about life and death.

In the Star Trek: The Next Generation episode “The Inner Light,” Captain Picard experiences a profound journey when his mind is transported into the life of a man living on a world facing destruction. Over just a short time on the Enterprise, Picard lives decades of this man’s life, all triggered by a strange probe that locks onto him and transfers his consciousness into a realistic simulation.

Picard is forced into this experiment, making it a deeply unsettling experience. The probe connects to his mind without his consent, throwing him into a completely immersive alternate life. In this other life, he fully integrates into the society of a world nearing its end, building relationships, raising a family, and living a full life that feels just as genuine as his experiences aboard the Enterprise.

This episode deeply impacts Captain Picard throughout the rest of the series, even changing how he interacts with children. He used to feel awkward around kids, but after living a life as a father in “The Inner Light,” he becomes much more open and accepting. While the episode is often remembered as touching and sweet, its heart is ultimately about sadness and loss.

Violations Is One of The Next Generation’s Most Disturbing Episodes

As a big Star Trek: The Next Generation fan, I always found the Season 5 episode “Violations” incredibly unsettling. It’s definitely one of the show’s darkest, dealing with really difficult themes like mental violation and the idea of someone losing control of their own memories. The story centers around these alien visitors, the Ullians, who collect good memories for research. But one of them, Jev, goes way too far and starts invading the private thoughts and memories of the Enterprise crew, which is just deeply disturbing to watch.

Jev attacks several members of the Enterprise crew. After a friendly chat with Jev, Troi goes back to her room to rest, but is plagued by disturbing dreams about her past relationship with Commander Riker. In her dream, Riker suddenly attacks her and transforms into Jev.

Dr. Crusher finds evidence of a psychic attack within Counselor Troi’s mind, and quickly becomes a target herself. Jev then compels Crusher to relive painful memories of her husband’s death. While reviewing medical data, Crusher experienced forced visions, demonstrating Jev’s ability to invade anyone’s mind at any moment, even while they’re awake.

The episode “Violations” stands out from most of Star Trek: The Next Generation due to its unusually dark themes. While the characters eventually heal, the psychic attacks inflicted by Jev powerfully represent the trauma of sexual assault. The episode’s honest and realistic portrayal of the characters’ reactions makes it a particularly impactful one in the series.

Conspiracy Explores Body Horror and Features One of Its Most Controversial Scenes

This episode was significantly altered or cut in some areas because of its graphic exploding head scene. Many fans consider it one of the show’s best and most unsettling installments, marking a turning point for the series. It moved away from the typical Star Trek style and introduced elements of horror and distrust that weren’t usually seen in the show.

As a huge Star Trek fan, I always thought “Conspiracy” was a really clever episode. It showed that the scariest threats weren’t always aliens, but could actually be lurking inside Starfleet itself. The story kicks off with Captain Picard getting a distress call from an old friend, Captain Walker Keel. They meet up, and Keel immediately tells Picard he’s worried about something going on back at Starfleet Command – it’s a really unsettling start!

Soon after meeting Keel, his ship is destroyed, prompting Picard to travel to Starfleet Command to investigate. There, he realizes something is wrong – many Starfleet officers are acting strangely. It’s discovered that these high-ranking officials have been secretly taken over by an alien parasite, similar to the premise of the movie Invasion of the Body Snatchers.

In the episode, Picard and Riker challenge Starfleet, leading to a showdown with Remmick. This confrontation includes a shocking scene: when Picard and Riker attack, Remmick’s head explodes, and a parasitic creature emerges from the burst open cavity in his chest. This event effectively ended the secure .
