"I'm sort of, in a way, the Grinch, who wants to steal Christmas away from all of these hard-working employees who are not doing as good of a job as they should be doing," Aniston says in a behind-the-scenes clip. "I know that I'm actually right. I just don't go about it the right way."
In the movie, when a CEO (Aniston) tries to close the branch run by her hard-partying brother (Miller), he and his Chief Technical Officer (Bateman) rally their co-workers and host an epic office Christmas party in an effort to impress a potential client who could save their jobs.
While the purpose of the shindig is to keep the branch afloat, everyone uses the party to serve their own personal goals. Richardson is a guy from legal itching to show off his skills as a DJ, Bayer is an executive assistant looking for love, and McKinnon needs to satiate her obsession with the holidays.
