The Grand is in the tradition of improvisational comedies like Best In Show and This Is Spinal Tap. The story is set in the world of professional poker and follows six players who reach the final table of the world’s second most famous high stakes tournament, the Grand Championship of Poker.
Psychiatrist Sam Foster has a new patient, Henry Letham, who claims to be suicidal. In trying to diagnose him, Sam visits Henry's prior therapist and also finds Henry's mother -- even though Henry has said that he murdered both of his parents. As reality starts to contradict fact, Sam spirals into an unstable mental state. Then he finds a clue as to how and when Henry may try to kill himself, and races to try to stop him.
