It's time for the annual Santa Summit, in which revelers put on Santa suits and hop around designated locations in town to eat, drink, and be merry. Three best friends decide to go together: Jordin (King), a recently dumped art teacher looking to cut loose; Ava, a shy woman hoping to run into her crush; and Stella, a Christmas cynic with no interest in the Santa Summit whatsoever. At the start of the night, Jordin meets and bonds with Liam (Hollingsworth), but doesn't get his name before getting separated and lost in a sea of Santas. As the night progresses and hijinks ensue, amidst the chaos, celebration, and a sea of Santas, they all find what they're looking for: Christmas spirit, potential romance, and a strengthened bond of friendship.
