The plot revolves around the serendipitous and unexpected romance between a young man and woman living in St.

Maksim is a young man with a degree in architecture who has moved to St. Petersburg from Nizhny Novgorod and who works part-time as a street sweeper.

Although Masha and Maksim have never met, they share a common trait: both have a tendency to be clumsy in daily life, always dropping and spilling things.

Masha is getting ready to marry her old schoolmate, Kostya, while Maksim has just won an international architecture competition and is preparing to move to Germany for a new job.

In the meantime, Masha begins to realize that she is not in love with Kostya and agreeing to marry him was a rash decision on her part, while Maksim starts to think that he would rather live in St. Petersburg than move to Germany.
