Derek and his lovely wife Amber are celebrating Christmas Eve by themselves this year, so they can reconnect in their marriage. They have a bottle of wine, the tree is decorated, and everything seems perfect.
Then the doorbell rings. Adam, Amber's co-worker stops by. Adam would love nothing more than the send the smarmy douche packing, but Amber already invited him inside. Things get worse when Adam offers Amber a massage, picking up right where he had interrupted the two of them. But a massage isn't the only thing Adam offers to his wife. Little by little, Derek watches as the stranger takes whatever he wants, right down to the ultimate act of betrayal, wondering why his wife seems to just go along.
