Jonathan Levine co-writes and directs this festive comedy starring Joseph Gordon-Levitt, Seth Rogen and Anthony Mackie. For the last decade, best friends Ethan, Isaac and Chris (Gordon-Levitt, Rogen and Mackie) have indulged in an annual Christmas Eve tradition that has seen them reunite for one crazy night of debauchery. As Isaac is expecting his first child and Chris's minor celebrity status makes it increasingly difficult to partake in wild antics, the group decide to call it a day... but not before having one final blowout.
