An unusual baby, a girl named Dominica, was dumped off to a perspective architect Kostia. Every time Kostia gets angry - the baby grows up...

Kostya (Andrey Chadov) is a successful architect, a modern representative of "decent" men. He avoids conflicts with his boss (Olga Dubovitskaya), does not violate law and order, and builds the "right" relationship with his girlfriend (Svetlana Ustinova). Everything changes when one evening at the door of the apartment he discovers a thrown child - Dominika, whose appearance changes his whole life.—Tango Papa
