They Will Kill You

Asia Reaves and her sister, Maria, attempt to flee from their abusive father, but are cornered at a store. Asia shoots him and is arrested, while Maria remains in his custody.

10 years later, Asia arrives at The Virgil, an exclusive high-rise building in NYC, posing as the new maid. She is greeted by Irish building manager, Lilith Woodhouse, who explains that the Virgil is 100 years old and occupied by the wealthy and elite. While sleeping, several masked intruders, including residents Kevin and Sharon, break in and attack Asia. They are shocked to discover Asia is armed and highly skilled at defending herself, managing to kill all of the assailants. Asia confronts Lilith and demands the location of Maria, who works as a maid at the Virgil. Asia's attackers resurrect, forcing her to seek refuge in the building's vents.

Kevin and Sharon give chase, but Asia manages to dispatch Sharon with a shotgun blast to the head. Asia is saved by Lilith's husband, Ray, who explains that The Virgil is a temple to Satan, and the residents have been made immortal by performing human sacrifices. The two travel up a floor, unaware they are being followed by Sharon's sentient eyeball. The two meet with Maria, who reveals she is aware of what is happening at The Virgil and does not want to leave. Asia knocks her unconscious, but she and Ray are attacked by the cultists. Asia and Maria escape up a floor via a dumbwaiter, while Ray is captured and tied up by Lilith and Sharon, whose head has started to regrow.

In the kitchen, Asia and Maria confront one another. Maria explains she fled their father shortly before he died from cancer, working at sleazy motels until she was hired at The Virgil. Although she was initially due to be a sacrifice, she was spared and now enjoys the relative comfort of the building. Lilith demands that all residents and staff track down the sisters. Maria saves Asia from a cultist before being captured. Asia pursues the cultists and slaughters most of them with a burning axe. The two try to climb to a fire escape via the elevator shaft, but are ambushed by Lilith and the cultists. Lilith reveals that, to gain immortality, Maria must make a sacrifice: the maid Asia was posing as.

The sisters and Ray are taken to the top floor, where the cultists summon Satan, who possesses the severed head of a pig to communicate, the names of the immortal cultists written on its skin. The pig removes Ray's name from its skin and forces Lilith to murder him, permanently killing Ray. It then instructs Maria to write her name and kill Asia. Instead, Maria writes Asia's name and kills herself. Now immortal, Asia repeatedly kills Kevin, Sharon, and the cultists. Lilith allows the severed pig head to take over her body and duels with Asia, who overpowers her and removes the head. She douses the pig's head in bleach and sets the pig's head on fire, removing the names, which results in the cultists all dying from their injuries. She then sets the pig's head on fire and flees with Maria's body.

Reuniting with an associate, Asia places Maria's body in the backseat, where she resurrects. Asia shows her that she has cut off her name from the pig's head and changed to Maria. Now reunited, the sisters drive off as the top floor of the Virgil explodes.
