Piotrus is always broke, and he's had enough of it. At night, he’s the star of an underground band; during the day, he works as a waiter in a hotel restaurant. When the opportunity arises, he decides to sell drugs to one of the exceptionally rich guests, Joan. A crazy night begins. During an exclusive corporate event, Piotrus is under extreme pressure, serving demanding clients, trying to appease his constantly dissatisfied boss, and finalizing the drug deal with Joan — all while being hungover.
