S4E22 · Half a Life

The USS Enterprise takes aboard Deanna Troi 's (Marina Sirtis) eccentric mother Lwaxana (Majel Barrett) and Dr. Timicin (David Ogden Stiers) of Kaelon II. Timicin is brought aboard to conduct an experiment, which he hopes will save his threatened home planet, as its sun is in a state of near-collapse. The Federation enlists the Enterprise to take Timicin to a sun in a similar state of decay to conduct experiments which may yield a method for saving the Kaelon system from destruction.

Upon arrival at their destination, the crew assists Timicin in modifying photon torpedoes to launch into the proxy sun, with the expectation that they will repair the damaged star and prove that the technique can be safely applied to the Kaelon sun. The torpedoes are fired and, although the experiment seems initially to work, the effect is short-lived and the star explodes. The Enterprise returns to Kaelon II. Timicin is crushed, and after some questioning by Lwaxana, he reveals that there are other things troubling him. Timicin tells Lwaxana that he is about to turn 60, and on Kaelon II, everyone who reaches that age performs the "Resolution", a required act of voluntary euthanasia.

Lwaxana is outraged to learn of this and brings it to the attention of Captain Jean-Luc Picard (Patrick Stewart). Picard makes it clear to Lwaxana that due to the Prime Directive, he will not interfere in the planet's local affairs. Lwaxana tries to beam herself down to the planet to halt the process, but she is thwarted by Deanna, who comforts her.

After Lwaxana and Timicin spend an evening together, he tries to explain the custom of the Resolution. He tells her that a fixed age had to be selected by the Kaelons, because just randomly choosing a time to die would be heartless. Lwaxana finds the practice barbaric and refuses to accept the Kaelon tradition. She tells Timicin how a Beta-Zed woman on her planet successfully fought the tradition of wearing ornate wigs that contained live, captive animals. It only took one courageous woman to step forward and end this cruel tradition. Lwaxana also compares Timicin's plans to end his life with his research to save his star. If it is Timicin's time to die, Lwaxana argues, perhaps it is time for his star to die as well, so why should he continue to try to prevent it? Timicin thinks about what Lwaxana has told him.

Timicin's analysis of the failed test turns up some promising options, but if he follows through with the Resolution, no one will have his experience and knowledge to carry on his work to save his world. Concerned, Timicin requests asylum on the Enterprise so that he can renounce the Resolution and continue his research. B'Tardat (Terrence E. McNally), the Science Minister on Kaelon II, is outraged after learning of Timicin's request for asylum, and he sends up two warships to ensure that the Enterprise does not leave the system with Timicin on board.

As Picard orders the bridge crew to analyze the offensive capabilities of the Kaelonian ships, Timicin realizes that his situation is not as simple as he had hoped, for his home planet will not accept any further reports from him, and he is told that even if he does find a solution, they will not accept it.

Dara (Michelle Forbes), Timicin's daughter, beams on board the Enterprise to insist that he return to Kaelon II and undergo the Resolution. She tells him that she cannot bear the thought of him being laid to rest anywhere but next to her mother and, although she loves him, she is ashamed of him. Timicin realizes that he is not the man to forge a cultural revolution, and agrees to return to Kaelon II. Lwaxana, despite her disagreement, realizes that Timicin's decision is his to make. As it is the custom for loved ones to be present at the Resolution, Lwaxana beams down to be with him at his side at the time of his death.
