Ever since the mid 1960s, Star Trek has produced a whole host of varied episodes, with topics ranging from inherently political commentaries, to lighthearted comedic relief, even challenging topical diversity issues right from the program's creation. These themes continued on throughout the various additions to the franchise, potentially most varied with the fan-favorite series The Next Generation. This series provided audiences plenty of different episode themes, and continued on the precedent that the Original Series set. One of the most memorably tragic and emotional episodes comes into play during season 5, with the episode titled “The Inner Light.”
The episode in question starts with well-loved captain Jean-Luc Picard and the crew of the USS Enterprise encountering an alien probe after a fairly standard mission in the Parvenium system. Upon scanning the probe, it emits a shot of energy directly at the captain. Picard collapses, only to wake up in bed, with different clothes, on an unknown planet. Startled by this dramatic change of scenery, things only get stranger, as an unknown woman tends to him and claims to be his wife Eline. She explains that his name is Kamin, and that he is an "iron weaver" who had been seriously ill with a fever.
Understandably confused, fearing this to be a trap, Picard refuses to accept this. He insists he is Jean-Luc Picard, captain of the starship Enterprise, and that he must find a way to contact his crew. He finds out they are on a planet called Kataan, and upon wandering outside with Eline, he discovers the members of the town they reside in all recognize him, and congratulate him on his recovery. He insists on his identity, but everyone around him fears him still delirious from the fever. Despite his fears they are trying to gaslight him into accepting his new identity (potentially a "four lights!" remembered trauma), everyone is so kind and thoughtful, and he peacefully starts to accept their words. He talks to Eline and what is supposed to be his close friend Batai candidly about the Enterprise and his true identity, but they insist that these memories were just dreams. While at first he still believes in his old identity, he decides to go along with it, and starts to try and figure out what is going on.
Years pass, and Picard takes up the flute to steady his mind, but his memories of the Enterprise slowly drift away. He never fully accepts he is Kamin, but has begun living as him, even if it simply started as his only option. Of course, Eline is worried, but always caring, trying to help the man she married to regain his memory of her. She and Picard grow close, and they even have children together, Picard finally starting to cement himself in his reality. As more and more years go by, he spends most of his time outside, crafting a telescope based on old Earth designs. At first, this was an attempt to seek out the Enterprise in orbit, but later it was reserved for the peaceful study of nature.
Things start to take a turn however, as Picard/Kamin observes strange things happening within their ecosystem. A drought, something that would be so easily fixed by a replicator, plagues the civilization and he and a team of colleagues investigates and discover that the sun is going nova. While still some time off, this disaster would completely wipe out the planet. However, when taking their evidence to those in charge, they simply brush off Picard as the delusional man they believe him to be, and things continue the way they have always been. 40 years pass, and the audience sees Picard as an old man. The drought is still happening, and things seem to have only gotten worse, as he has outlived his beloved wife Eline and his friend Batai. Things are not all bad, though. In this time, he has become a grandfather, a well respected elder of the town, and a renowned flute player.
Working with his daughter Meribor, they come to the horrible concussion that there is no way to stop the sun going nova, and that the extinction of their planet is unavoidable. They confront the governing bodies about this once again, and they brush him aside, but this time one of them takes him aside and tells him the truth. They have known about this for a while now, but have kept it from the public to avoid mass hysteria. They have been working on space travel and the idea of evacuating the population, but their civilization is not advanced enough to do it in time. Their technology is primitive, and they don’t have enough time, even with Picard’s knowledge of space travel.
More time passes and now Kamin/Picard is very old, even older than seen in Picard season 2. He is shown playing with his grandson, until his children arrive and slowly walk him to watch the launch of a rocket, something everyone seems aware of but him. In the blinding light two figures emerge, a young Eline and Batai. As Kamin/Picard is beside himself with joy, they tell him that he has already seen this rocket before, right before he woke up on the planet. Confused, with his memories of the Enterprise so faded, they explain that when they realized that their planet was doomed, they decided to use what limited knowledge of space travel they knew to launch a satellite into space. The satellite was a time capsule of sorts, containing the memories of the people who lived there and the lives they have lived, and that hopefully it will find its way to someone who can remember them. It dawns on Picard: “Oh, it’s me, isn’t it?” realizing it was Kamin’s memories they used for the satellite.
And in the space of a Q's finger snap, Picard wakes up on the bridge of the Enterprise. The decades he had just lived through, each and every second of it, had only taken place in 25 minutes. Regaining his stature and memories of his previous life, the crew bring aboard the now powerless satellite. Inside it is a small box, which Riker brings to Picard privately. Inside is Kamin’s flute. The episode ends with Picard picking the instrument up, and remembering the simulated life he had lived, of his wife and children, good friends, and begins playing a beautifully sad lament on the flute as the credits roll. The episode is a masterpiece, and shows the emotional depth Star Trek can reach when paired with great storytelling and a well-loved character.
