Paris Trout is a vile Southern bigot. He owns a store and is a loanshark. He often sues people, and so his lawyer, Harry Seagraves, eventually meets Paris' wife Hannah. A former schoolteacher, she made the mistake of her life when she married Paris, who brutalizes her. Soon Paris goes beyond the overgenerous bounds of what a man in his position can get away with even in the segregated South, leading to a spiral of perverse insanity.

Based on the true story of an Alabama woman who was convicted of killing her first husband and attempting to poison her daughter. Out on bail, she flees in order to start a new life with two new identities.
