Doug Heffernan, chauffeur-livreur, et son épouse Carrie, secrétaire dans un cabinet d'avocats, mènent une vie paisible dans le Queens (quartier de New York) jusqu'au jour où l'excentrique père de Carrie vient s'installer chez eux…
It's Thanksgiving in the Heffernan household and while Carrie cooks dinner for ten people, Doug lets a stranger into the house to use the phone. He is convinced the stranger is a nice guy but Carrie is not so trusting. Everyone at dinner feels sorry for the man, who's been left outside to wait for a ride, but when Carrie finally gives into the holiday spirit, it turns out her instincts may have been right.
