A department manager has to defend himself in court against charges of harassment in the workplace. Looking back, he describes his tough day at work to the judge.

Willi Schulze is a car mechanic. Together with Paul, who escaped from an orphanage, he runs a garage. During the testing of a car, Willi finds out the brakes aren't working that good. A fatal accident can just be prevented. He tries to hitchhike home and gets picked up by American election expert Willy Schneider. Together they also get an accident and both lose their memory. The police assumes Schulze is the election expert and rapidly he turns into the pivot in a stone-hard election-contest.
