Ten-year-old Ole is full of mischief. He attempts to fly and is hospitalized with a broken leg. When he sees a Sherlock Holmes movie on TV, however, he forgets about the pains and comes up with a new plan. Disguised as Sherlock Holmes and Dr. Watson, he and his friend Andreas start searching for criminals. Soon, the two boys detect their first case. On the street they meet a man wearing a stuck-on beard. The hobby detectives find this very suspicious and decide to follow him. Ole and Andreas are supported by their classmates. Eventually, Ole helps the police to arrest the man who was actually wanted for thievery. Although they have put themselves in great danger, the criminalist Vogel compliments Ole and Andreas for their help.
