What To Watch On Netflix: No One Gets Out Alive
From Wikipedia:
Ambar, an undocumented Mexican immigrant, moves to Cleveland after the death of her mother. She used to take care of her ailing mother and could never live a normal life, as her mother continuously became sick until she relocated to the United States to support her. She finds a dilapidated boarding house run by Red, who demands the first months rent up front, which Ambar gives from a reserve of cash she seems to have saved up for her move. Odd things start happening to her at the new boarding house and out of it. She gives a co-worker the remainder of her savings to obtain a fake ID that will allow her to continue working at her job. The co-worker betrays her, taking the money and quitting the next day.
Unable to receive help from Beto, a distant cousin, and not wanting to return to the house after the visions, Ambar is forced to call Red. They meet at a nearby cafe and Red promises to refund her deposit, but only if she returns to the house, as he claims he does not have enough cash on him. When they return to the boarding house, Ambar confronts Red as the cash is not in her room as promised. Becker, Red's brother, forces Ambar into her room, and she locks herself inside. She is joined in the room by two other Romanian women who are living in the boarding house.
As Red and his brother, Becker, are planning to take the women down to the basement, Beto comes looking for her, but is killed by Becker. Becker commands Red to "prepare" her and the other girls. Red tells her that his dad was an archeologist who brought back a stone box from one of his trips. Something about the box inspired Red's father, along with his mother, Mary, to trap and murder women (the ghosts that Ambar has seen throughout the house). When Red and Becker arrived home after a while, they saw what their father had done. Red wanted to leave, but Becker wanted to stay. Something about sacrificing women to the box improved Becker's health.
Ambar struggles against Becker as he takes her down the basement. Becker ties Ambar to a stone table in front of an altar where the box sits. After tying her up, Becker opens the box and leaves the room, shutting the door behind him. Ambar begins dreaming about her mother on her deathbed, while a creature slowly emerges from the box and attempts to eat Ambar's head. Ambar is able to wake herself up by killing her mother in the dream, and, by doing so, causes the monster, which seems to be the Aztec goddess Ītzpāpālōtl, associated with the moth seen in the movie, the Rothschildia erycina, to retreat back into the box.
Ambar hears Becker and Red preparing one of the other immigrant women for sacrifice. She grabs an ancient weapon from the study and goes upstairs. She injures Red and is attacked by Becker. The other immigrant woman tries to help but is killed by him. Amber then kills Becker with the ancient weapon. She hears Red shuffling around in the next room and manages to get him downstairs and tied onto the stone table, where the monster bites off his head, killing him. As she is leaving the house she realizes she has nothing left but is suddenly healed from sacrificing Red to the monster in the box. In the background, Red can be seen as a ghost.
