Martin, a poor student, volunteers to go on a quest to find a cure for the princess Adriana, who is stricken with a strange illness. Unknown to Martin or anyone else, the princess is actually under the spell of the powerful magician Andlobrandini, who is preparing a rejuvenating elixir made from the blood of nine men's hearts.

At the end of August, a young woman is chased by an angry mob of hooligans under the windows of a bus because she decides to tear down a poster grossly insulting her husband, the staunch communist and deputy Balcar. She only gets a defence from the prosecutor Ronešová, who decides to convict and prosecute the perpetrators and bystanders of the unfortunate event. The principled Ronešová is oblivious to personal problems and sets out to fight against the relics of a happily extinguished social movement, with the right-wing defence lawyer Kahan being no match for her.
