Harry's faithful, but emotionally cold, wife has become all but impossible to love. Smitten by the young and beautiful Kay, the emotionally fractured husband becomes terrified at the prospect of exposing his spouse to the social humiliation of divorce and decides poisoning her is the only morally decent option. But when Harry confides his intentions in conniving best friend Richard, the scene is set for a noir-like drama in which few, if any, will find peace.
