Wealthy-but-troubled Vietnam vet Jeff Fahey, his trailer-trash wife Karen Allen, and drifter John Carradine are the characters essential to the action in Backfire. Fahey's horrific flashbacks to his days in Nam plunge him into a catatonic state. Though he has previously drawn up a document granting his wife power of attorney in case this should happen, Fahey's protective sister Dinah Manoff keeps this fact secret, hoping to cut off the mercenary Allen--and her lover Dean Paul Martin--without a penny. Drowning her problems at a local bar, Allen makes the acquaintance of Carradine, who shortly afterwards moves into the family mansion, bag and baggage. Fed up with being treated like garbage, and equally fed up with her noncommunicative husband, Allen enmeshes Carradine in an insidious plan that will regain her the riches she feels she deserves. And you'll get no more out of us at this point. Those who associate Karen Allen with her tough-but-honest heroine in Raiders of the Lost Ark are in for a jolt as she goes through her Lizabeth Scott/Barbara Stanwyck/Jane Greer paces in Backfire.
