On a peaceful holiday night, Kiersey and Benji-- a couple in an ethical non-monogamous relationship-- are awoken by an errant dildo that shatters their bedroom window. The perpetrator outside is Jacqui, Kiersey's secondary partner, who is drunk and on an ill-conceived mission to establish her romantic dominance. In the spirit of the season, Kiersey and Benji take pity on Jacqui and invite her inside to sleep things off on the couch, and are forced to deal with a series of inebriated confrontations and revelations that challenge the status of their relationship.
