Death in Winter (Star Trek: The Next Generation)

Long before Captain Jean-Luc Picard took command of the legendary Starship Enterprise, he fell deeply and hopelessly in love with Doctor Beverly Crusher. Though, for one reason or another, Picard never acted on his feelings, he found a measure of contentment as Beverly's close friend, colleague, and daily breakfast partner. But when Doctor Crusher leaves her position on the Enterprise to become the chief medial officer of Starfleet, the brightest light in Picard's life is taken from him. And he has hardly resigned himself to his loss when he learns that Beverly has been declared missing in action on a distant planet - and presumed dead.
