In Christmas Staycation, the dysfunctional family members decide to connect with each other through an online video chat on Christmas day. They try to keep things normal by having a virtual gift exchange, preparing and sharing meals, and playing games that they used to enjoy when they were together in person.
However, as the hours go by, things start to get weird. The family members keep bringing up old conflicts and grudges, and arguments quickly escalate into full blown fights. One family member accidentally reveals a deep secret that causes chaos in the family. Another brings up a conspiracy theory that leads to suspicion between family members.
As the day wears on, the family members start to lose their inhibitions and say things they normally wouldn't say. They start to dress up in silly costumes, sing karaoke, and dance around their living rooms. Despite the chaos and dysfunction, they realize that even though they couldn't be together physically, they were still able to connect and have fun in their own unique way.
In the end, the family members log off their video chat feeling a bit drained but also closer to each other. They realize that, despite their disagreements and quirks, they still love and care for each other and that they can always find ways to be together, even if it's just through a screen.
