Jos (Pepón Nieto) has been sent by the employment agency as an extra for the tapings of a New Year's Eve television special (four months in advance) in an industrial pavilion just outside Madrid. Hundreds of people like him have been locked in there for weeks, applauding for musical performances they don't actually see and celebrating the false arrival of the new year. As he's starting to fall for his dinner companion Paloma (Blanca Su rez), he doesn't know two major clashes of egos are unfolding backstage. On one hand, veteran crooner Alphonso (Raphael in a self-parodic role) comes face to face with his bitter rival, Latin pop sensation Adanne (Mario Casas) as both of them are determined to get the most watched performance of the night. On the other hand, the two co-hosts of the show can't stand each other and fight over the trust of the producer Ben tez (Santiago Segura), who is aware the channel is struggling to avoid its closure.
