High school chemistry and physics professor Samo Demšar is an exceptional educator who always sides with his students. Personally, he's an eternal young man and a teenager at heart, which is why he understands his students so easily. However, he often finds himself in trouble. Typically, because women like him at least as much as he likes them. At first glance, it seems that the new high school teacher, the attractive Klavdija Jaklič, is going to be the exception. She is very happy to help Sam solve various problems faced by growing students.
