Three friends, hungry for sensations and male company, go out to the city to have fun on the shortest night of the year.

When an explosive plant at a gas station kills a police sapper, the chief police officer assigns Gebels from the homicide unit to the case. The investigation leads him to the trail of a criminal from the armed arm of the Pershing group - a bomb maker and kidnapper, behind dozens of attacks in Poland and over a hundred kidnappings across the country. The confrontation between the bandit and the dog turns into a regular war. Years have passed since these events. The son of Gebels, known from the series, Jarek, who is a computer science student at the Polytechnic University, together with his friends finds a risky way to earn a quick income and, using his knowledge, starts breaking into the villas of rich people. Bad luck wants him to choose the wrong house one night, and Gebels faces a hopeless situation in which he has to put his own child in prison. Could be a policeman who arrests a criminal. Or a father who will save the child.
