Tatjana, Iva, Julija and Mirjana celebrate Maša's thirtieth birthday in the Angel Bar outside of opening hours. The party is unexpectedly disrupted by a policeman who shows up at the door of the bar, but nothing can stop the playful girls. They misinterpret the arrival of a man and consequently behave incorrectly and inappropriately towards him. They land at a police station for disturbing the peace and order, and they are also threatened with a civil lawsuit by a police officer. Shocked, the friends ask Tatyana's husband Klemen, a cosmetic surgeon, to provide them with a good lawyer.
