Otto is Friesland's answer to Rambo and stands between two worlds, two women and two animals. While he's trying to cure a dog with bite inhibition and a cat with suicidal tendencies, the dream of his sleepless nights crosses his path: Gaby. Otto falls instantly in love, but Gaby thinks only of Amboss, a real guy with muscles of steel and a brain of rubber. Well, Otto on the other hand is not exactly well built and attractive. But he's determined to get the lady's attention, even if it means taking part in body-building competitions...
