Ali en Graham waren enige tijd gelukkige geliefden en stonden zelfs op het punt te gaan trouwen. Inmiddels zijn ze niet meer samen. Wanneer Graham besluit om zijn familie te verrassen door naar huis te reizen voor Kerstmis, is hij geschokt om te ontdekken dat ze het al vieren met een onverwachte eregast: zijn ex-verloofde Ali. De twee exen gaan vervolgens de strijd met elkaar aan om te zien wie van hen mag blijven tijdens de kerstdagen en wie er moet vertrekken.
Nee, helaas is EXmas nog niet beschikbaar op Netflix in Nederland.
