Just as Frank and Marie are about to embark on a high seas vacation, Frank hurts his knee and Ray, not wanting to disappoint his mother, agrees to accompany her on the Caribbean cruise. It’s endless hours of shuffleboard and bingo and an extremely cramped cabin for two that can barely fit one. Could things get any worse for Ray? Marie, meanwhile, is having the time of her life soaking every ounce of fun in the sun. And back home, Robert is just about out of patience as caretaker for the injured Frank.
