The plot revolves around a boy who discovers that he is able to pull an infinite number of banknotes from the pockets of his jeans.
The biggest problem in the beginning is how to be able to exchange all their small bills into larger denominations without drawing attention.
Soon, newspapers and radio news feature stories about the authorities' efforts to reveal the "man without fingerprints."
Mats and his father, Torkel, then establish the "Fund for Orphaned Children" and fly to a developing country in Africa to donate large amounts of money there.
After an alcohol-fuelled evening, the father lets the truth slip to a German journalist, and Mats is finally caught by three hired villains who force him to give up his golden trousers, who then burn them.
