I bet anyone can get better at golf than you are in one week, a golfer says to her golfing businessman for a boyfriend in a quarrel. Unfortunately Stig-Helmer is standing nearby when the boyfriend accepts the bet, and he is chosen to be the competitor. Stig-Helmer has never played the game before, but his Norwegian friend Ole promises to help him.

Gösta Eriksson, a hairdresser, buys a car from used-car dealer Bertil Planåker. But Gösta soon discovers that the car is a wreck. Planåker won't give him his money back, in fact he denies ever having seen Gösta. Gösta's brother Rolle is released from prison and promises to help him. They form an investment company, Parabola, and convinces Planåker to invest a lot of money in it. Planåker has a lot of shady business colleagues who also invest their money. Gösta's and Rolle's scam becomes much bigger than they had bargained for.
