March 15, 1939. The luxury department store 'Golden Swan' opens in Prague on the very same day German troops cross the Czechoslovak state border. The thief Bára gets into the store while escaping from the police. Following a series of accidents and mistakes, she becomes a saleswoman in the fashion department and a new life opens up for her.

Soon the charming owner Petr, son of the Kučera family, notices her. They fall in love with each other, but the match is so obviously unequal. And amid war times, will love be stronger than the struggles to carry it through?
