The episode "Guantanamo by the Bay" is described as such: "Alan Shore sues the United States on behalf of a client who was tortured for two years at a detention camp. Meanwhile, Jerry Espenson begs Shirley Schmidt to let him have his job back at the firm — despite the fact that he'd once tried to kill her — and Claire defends a lawyer who committed a sexual assault after hearing a prank radio program proclaiming the world was coming to an end."
