 On the death of her stepfather, cynical sexy young Dedee Truitt heads off and moves in with her gay schoolteacher half-brother Bill. Seducing his partner Matt, she then announces she is pregnant, and disappears with him. Bill meanwhile is falsely accused of past sexual misconduct at school by one of Matt s ex-lovers, causing much media attention. As the situation snowballs, the only person who sees what Dedee is up to is Bill s rather frustrated acid-tongued sister-in-law Lucia.
