Conflict is a love triangle with murder at its heart, an atmospheric film noir of rainy nights, looming shadows, fatal romance and a trench-coated killer that walks out of the mist — all directed by Curtis Bernhardt, a filmmaker skilled in the Expressionistic style of his native Germany. The story embraces the perfect noir topic: the almost-perfect crime. Humphrey Bogart portrays Richard Mason, married to nagging Katherine (Rose Hobart) but in love with her sunny sister (Alexis Smith). Shortly after a fifth-year wedding celebration at the home of a friend (Sydney Greenstreet), Richard decides to remove the obstacle to his happiness. He kills Katherine, carefully leaving no evidence of his guilt. Or at least he thinks he killed her — until mysterious events cause Richard to fear Katherine is very much alive.
