An ardent bachelor Petro pledges with his best friend Oleh on the “Porsche”, which will be able to live for a month under one roof with a woman. So Veronika appears in his loft – an elegant music teacher, Oleh’s younger sister, whom Petro has known since childhood. She left her husband, a tyrant, and for the next month was busy looking for work and a new home. But a surprise for Petro is the appearance in his house – children of Veronika, thugs, sophomores, who turn the life of a macho upside down.
