Against her father’s wishes, the ringmaster Wallner, Helga forms a connection with the wild animal trainer Peter. After he is almost killed during an appearance, he promises his mistress, that he’ll never work with wild animals again. From that point on, he works with Helga on safe horse numbers. When Helga finds out from Peter’s friend Otto, that Peter would rather work with wild animals again, she doesn’t want to stand in the way of her beloved’s dreams. Helga disappears and leaves Otto enough money to buy Peter a new group of lions. For a long time, Peter and Helga do not see one another, though neither can forget the other. When Helga hears from Otto one day, that Peter is practicing a very dangerous number involving wild animals, during which Otto is to play the “lead”, Helga makes a fatal decision, so she might see Peter again.
