One night, Arya goes to a party and is abducted and sexually assaulted by Jagan and his gang. When Arya returns home bruised and traumatized, Devki tries to file a complaint with the police, but they refuse to help because Jagan is the son of a powerful politician.
Frustrated with the legal system, Devki decides to take matters into her own hands and hunt down Jagan and his gang.
