Everly

Everly (Salma Hayek), a prostitute working for the brutal criminal overlord Taiko (Hiroyuki Watanabe), is being 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.

Everly is caught by The Sadist (Togo Igawa) and some of Taiko's henchmen and tied up in a room. During Everly's torture, Edith bursts in with a gun and kills 2 of The Sadist's torturers, but is subdued by The Sadist while he performs the same torture as he did with Everly on her. Everly desperately struggles to escape and help her mother. She breaks one of the ropes that The Sadist had loosened before and uses her free hand to kill one of the assailants with a hidden gun. When The Sadist realizes she has a hidden gun, she shoots him twice in the lung. The last torturer runs toward Everly with a weapon, only to die when she shoots him in the chest and neck. She escapes her remaining restraints and goes to help Edith. The Sadist stands up (being still alive) and knocks Everly down, and is about to kill Edith when Everly forces a poisonous liquid down his throat, melting his intestines out of his stomach which kills him.

As the film progresses, it is revealed that Everly was a prisoner in the plush apartment after having been kidnapped by Taiko four years earlier and forced into prostitution. She has had no contact with Edith or Maisey during that time, and they are confused and angry at the deadly situation they are suddenly thrust into. As Everly fights off the numerous attacks, the foes become more outlandish; originally they are simply armed thugs, but eventually they appear in costumes and with themed groups for extravagant tortures.

Eventually, Edith is killed by a sniper hired by Taiko from the building across from the apartment. Everly is finally subdued, but manages to kill Taiko after his soldiers have left. Afterwards, Everly reconciles with Maisey, who was under the protection of one of Everly's neighbors, who was eventually killed. The film closes with Everly seemingly succumbing to her wounds, but with Maisey still alive and potentially safe with the death of Taiko. However, immediately before the credits, there is audio of a beeping heart-monitor and gasp of breath to indicate that Everly has not died after all.
