Everly (Salma Hayek), a prostitute working for the brutal Japanese criminal overlord Taiko (Hiroyuki Watanabe), is attacked in her apartment by Taiko's enforcers after he discovers that she has been working with the police to bring down his organization. However, though Taiko expected his men to kill her easily after torturing her, Everly retrieves a gun she had hidden and manages to kill all of her attackers. Taiko then begins a sadistic game of toying with Everly, dispatching numerous hired killers and offering the other prostitutes in the building (which he presumably owns) a bounty if they manage to kill her. Meanwhile, Everly attempts to contact her mother Edith (Laura Cepeda) and young daughter Maisey (Aisha Ayamah) to save them from other henchmen of Taiko and get them out of the situation alive.
