Steel Butterfly (Russian: Стальная бабочка, romanized: Stalnaya babochka) is a 2012 Russian crime film directed by Renat Davletyarov. Runaway street children led by Chuma rob various people in order to survive. Suddenly they are caught by the police and now Chuma is forced to become the bait for a serial killer.
Plot
In Moscow, teenage runaway Vika Chumakova, known as "Chuma", escapes from a state orphanage and sustains herself through petty crime with a gang of street kids. After they commit a robbery in a park, the group is apprehended by the police, landing Chuma in the precinct where she meets Captain Grigory Khanin. Khanin and his team are investigating a series of brutal murders targeting young girls with artistic ties, all occurring in isolated parts of the same park. Suspecting a serial killer, Khanin devises a plan to use Chuma as bait, promising her freedom if she cooperates but threatening to send her to juvenile detention if she refuses. Chuma agrees, on the condition that she be released until morning and that her confiscated switchblade be returned. Throughout the investigation, she navigates complex relationships with her street friends and manipulates those around her, including Khanin, with flirtations and provocation.
As Chuma continues aiding Khanin, their dynamic grows increasingly tense and complicated.
