The film stars Salma Hayek as the title character with Akie Kotabe, Jennifer Blanc, Masashi Fujimoto, Togo Igawa, Gabriella Wright, Caroline Chikezie, Laura Cepeda, and Hiroyuki Watanabe in supporting roles.

Taiko then begins a sadistic game of toying with Everly, dispatching numerous hired killers and offering the other trafficked women in the building (which he presumably owns) a bounty if they manage to kill her.

As Everly fights off the numerous attacks, some of the foes become more outlandish; originally, they are simply armed thugs, but the Sadist's team appear in costumes and plan for extravagant tortures.

When the sniper shoots a rocket-propelled grenade into the apartment, Taiko beheads him in anger, believing that he killed Everly, though she survives.

The film closes with Everly seemingly succumbing to her wounds, but with Maisey still alive and potentially safe with the death of Taiko.

The site's consensus states: "Everly benefits from Joe Lynch's stylish direction and Salma Hayek's starring work, but it's too thinly written and sleazily violent to fully recommend.
