It's Thanksgiving, and Marty's arrival home is greatly anticipated by his mother, his twin sister Jackie-O, and his younger brother Anthony. He arrives during a hurricane, but worse than the storm is the fact that Marty brings his fiancée. Marty's engagement is a threat to the well-being of this family and a greater threat to Jackie-O, who has always wanted her brother for herself. On top of that, Jackie-O has just recently been released from a mental hospital, Anthony dropped out of Princeton, and their mother has a serious
problem handling any of this.
