Sanction

To catch a rampaging serial killer in Soviet era Leningrad, two detectives must match wits with the murderer while battling the oppressive rules of their own police force and a greater, hidden enemy.

Leningrad, 1987. When a woman's corpse is discovered on New Year's Day, a hungover Detective Pavel Smirnoff hands off the case to his partner, Detective Boris Dimitrovich, hoping he'll close it without fuss. Instead, Dimitrovich uncovers a connection to an old, unsolved crime, dragging them both into an investigation that puts their careers - and possibly their lives - at risk.
