Bill Clark (Steve Cochran) is a brooding, fresh-from-the-pen ex-con who has spent his entire adult life behind bars. Upon discharge, he is a newborn in a fast, unforgiving world. When a reporter posts a front-page story on his release he has no recourse but to leave town. He heads to New York for a fresh start, but finds more complications in the form of Catherine (Ruth Roman), a steely dancehall dame. Their blossoming romance is almost nipped in the bud when Catherine's cop ex-boyfriend is shot and killed during an altercation with the pair. They take it on the lam with their reputations and past deeds not far behind. From out of the film noir shadows comes Tomorrow Is Another Day, a frank and forceful tale of fugitive lovers in an unforgiving world.
