Vera Donátová (Truda Grosslichtová) has finished her law studies and wants to found her own law firm. She is financially dependent, however, on her family. Her emancipated mother supports her endeavors but her father provides her the money with the condition that if her practice does not succeed within a year she will marry Consul Raboch's son. Vera has no clients. Her first case is assigned to her ex officio. Vera visits her client, Petr Kucera (Oldrich Nový), known as Tiger, in his prison cell, and against his will she obtains his release.
