When a disabled ship's tiny crew is brought on board the Enterprise, they assume they have been kidnapped and mistreated. They are Talarian's except for one, a handsome, blonde teenaged boy. He considers himself one of them and fears the crew. It turns out that when he was a little boy, the Talarians killed his parents. His only living relative is his grandmother who happens to be an admiral in Starfleet. He is put in a different setting than his crewmates and Picard, reluctantly, becomes his mentor. It is eventually revealed that the Captain of a Talarian vessel adopted him after the fatal battle. He wants his son back. The issue becomes, how do we treat someone who has only known one way of life. The initial effort is to return him to his childhood roots. He understands this but it miserable with it. He is also expected to act as those on the Enterprise do. The alien Captain gives Picard an ultimatum. Give the boy back or face all out war with heavy casualties. An interesting dilemma and worth a look.
