A psychotic man opens fire in a diner, murdering numerous people before killing himself. The survivors struggle in different ways following this horrendous event: a doctor doubts his own instincts and elects to use an experimental medical procedure on his wife, while a gambler believes he's on a lucky streak. A waitress begins engaging in promiscuous sex, and a young girl whose father is among the dead gains unexpected fame.
Not long after they cross paths at an art gallery, architect Ray Reardon and hypnotically sensual Lena are married with children. But as strange incidents occur, Ray begins to realize he may not really know the woman he married.
