Senior Lieutenant Kchura is on a new case. A body washes up near the railway lines, unidentified. Inside the victim's bag, forensics discover traces of an unknown synthetic drug, the kind used in the back-alley production of "Spice."

Major Tereshko, head of the Investigative Department, dispatches a team, including Karina Bartosh, a fresh-faced investigator from Minsk. Local beat cop, Andrei Kchura, is also pulled onto the task force.
