Jonny Wilken is an ageing lion trainer in a circus. He is in love with his younger colleague Jutta Sarris. On her wedding day, Jutta's favorite Bengal tiger attacks her out of jealousy and kills her. Jonny, full of pain and out of revenge, enters the cage to kill the animal with his bare hands. However, the tiger bows to him without any resistance.

Harry Piel plays Harry Peel who receives an urgent telephone call from a friend who has returned from South America recently. The call is being made from the circus "Beely" and our hero arrives there too late to prevent the murder of his friend. Now Harry must find his friend's killer and go on a strange mission involving a hidden document.

Prince Valona has a bit of trouble with his girlfriend Eveline (Olivia Fried), so he's quite open for the attraction of a young lady he meets by chance (Valerie Boothby). He doesn't know, however, that this lady is a detective who follows the con-man Carlo Moreno, and as the prince and the criminal look alike, she mistakes the prince for the criminal. The real Moreno isn't far away, though, and he first deprives the prince of his train ticket and then also takes on his identity in order to steal a pearl necklace from Eveline.
