Ole Söderblom

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.

The landlubber Stig-Helmer and his Norwegian friend Ole get on a barge by mistake. They arrive at an archipelago and have to spend Midsummer among the fancy rich boat people, their yachts and summer houses.
