Hömpstad, an imaginary town, has been swept by a crime wave. Brazen crimes and robberies are now a reality for the people in the town and the police would need a superhero to help them. Vinski, a 10-year-old boy, meets a mysterious pharmacist who gives him a bottle of magical powder. The powder allows you to become invisible and walk through walls. At first, Vinski uses his new powers for practical jokes, but with the help of the pharmacist, he also begins helping the local people. It is fantastic to have superhero powers but for Vinski’s misfortune, a nasty band of crooks soon becomes interested in the secret of invisibility as well.
