Thirty-something Jonas is not doing well at the moment. He has been taking antibiotics for a long time, so he is out of shape, and the trainer does not nominate him for the upcoming boxing match, he had a fight with a homosexual customer at work and is facing criminal charges because of that, and he also got a little involved with his colleague Silva, which logically does not please Jonas's friend Klařá. But Jonas hides the biggest problem by far from everyone. Although the suspicion of rectal cancer is fortunately not confirmed, the method of treatment of the damaged colon nevertheless shocks him - he has to regularly insert a dilator into his ass!
