What if your mother were about to marry your worst nightmare, the man who tormented your youth, who still haunts your nightmares--Mr. Woodcock? John Farley (Seann William Scott--The Dukes of Hazzard), author of a best-selling book about letting go of the past, violates his own advice when he returns home to accept his community's highest honor. There, he learns, to his horror, that his widowed mother (Academy Award winner Susan Sarandon - Shall We Dance?) is engaged to his old high school gym teacher, Mr. Woodcock (Academy Award winner Billy Bob Thornton--Bad Santa), whose sadistic acts plagued John's youth. Now, abetted by his nerdy old pal Nedderman (Ethan Suplee--The Butterfly Effect), John will stop at nothing to derail the relationship.
