Brian Donlevy stars in this hard boiled noir as Walter Williams, a wealthy industrialist who is unfortunately also a cuckold. Desperate to get rid of him, his two-timing young wife, Irene, and her lover plan Walter's death, only to have their scheme go horribly awry. Walter survives, and ends up in Larkspur, Idaho with a nasty case of amnesia that begins to clear when he sees stories about his own death in the newspaper. Having fallen in love with a girl in Idaho, Walter goes back to his wife to confront her, only to be charged with murder himself. Filled with smart, arch dialogue, back stabbing women, and numerous plot twists, IMPACT is a hugely entertaining noir.
