Katya Petrovskaya, an employee of the press center of the Internal Affairs Directorate, got a strange vacation. Together with her husband Vadim Kravchenko and their friend Sergei Meshchersky, they arrived at the Baltic resort and on the very first day witnessed a ferocious and mysterious murder. This was not limited to this - a few days later they found a dead teenage girl. As Katya found out, such "incidents" with young girls are not new here. But the killer, like a ghost, leaves no evidence.
