Premise

A time-travel experiment that went wrong sends physicist Sam Beckett back in time, where he assumes other people's identities and helps to resolve the crises of his new hosts. He's assisted in his adventures by Al Calavicci, also known as `The Observer,' who has the ability to appear in holographic form. The imaginative, Emmy-nominated series spawned a reunion TV-movie, `Quantum Leap: A Bold Leap Forward.'
