Jack was living an almost perfect life, with the exception of one, annoying constant - his twin sister Jill. Every year he has to tolerate a Thanksgiving visit from his smothering sister, who doesn't take long to turn his life upside down. As the weekend intrusion starts stretching into a month, the siblings fight, tease, and bicker in the way only twins can. When it becomes clear Jill is never leaving, Jack sets into motion several schemes that he hopes will return Jill to where he loves her most - the other side of the country.
