April 14, 1953: With looks that could double for Humphrey Bogart, Sam is Nick Allen, a private investigator looking for the murderer of his partner and, if he doesn't find the answer in time, himself. The case is solved with a number of Casablanca references as Sam launches a new pulp novelist along the way.
Theorizing that one could time travel within his own lifetime, Dr. Sam Beckett stepped into the Quantum Leap accelerator and vanished... He woke to find himself trapped in the past, facing mirror images that were not his own and driven by an unknown force to change history for the better. His only guide on this journey is Al, an observer from his own time, who appears in the form of a hologram that only Sam can see and hear. And so Dr. Beckett finds himself leaping from life to life, striving to put right what once went wrong and hoping each time that his next leap will be the leap home.
