Thanksgiving is usually a happy time, but ad executive Jack (Adam Sandler) dreads the holiday because his twin sister, Jill (also Sandler), makes her annual visit.

But, when actor Al Pacino (Al Pacino), whom Jack desperately needs to star in a commercial, takes a shine to Jill, Jack may be forced to extend his sister's visit even longer.
