Inspired by a real event, the Militia Police Commander assigns a homicide case to officers Nogas and Robert. A wealthy man named Adam Gregorczyk is brutally murdered in the park, and high authorities demand a conviction. Robert and Nogas search Gregorczyk’s house and find obscene flyers and VCR tapes in his house.
Nogas concludes that Gregorczyk was a queer as his dead body was found near a gay bar called Mushroom. The officers raid the bar and arrest a few queers for interrogating them. In the center of the conflict is a righteous militia Sergeant, Robert Mrozowski, who discreetly investigates the hitman killing gender minorities in Warsaw.
