Hank Grotowski (Billy Bob Thornton) lives with his aging, white-trash father Buck (Peter Boyle), and his twentysomething son Sonny (Heath Ledger) in a backwoods Georgia town. Hank and Sonny are both correctional officers in a state penitentiary that routinely executes prisoners by means of the electric chair. Being more experienced, Hank becomes a mentor to his son, showing him the ins and outs of prepping prisoners on death row and warning his son never to become attached to the inmates. But Sonny becomes deeply affected by the execution of Lawrence Musgrove (Sean Combs), a black man with whom he has bonded. This doesn't sit well with Hank, who believes inmates and guards should have limited contact, and creates tension between father and son. Then, in a bizarre twist of fate, Hank meets and becomes involved with Laticia (Halle Berry), a black waitress at a local diner who, unbeknownst to him, is Musgrove's widow. Their neediness brings them together and although they are both somewhat dysfunctional, their unexpected relationship brings out the best in them and melts away obstacles that may have otherwise kept them apart.
