The rookie officer Jessica "Jess" Loren is the daughter of a deceased police officer, and her mother is against her wish to work to the police. On her first assignment, she heads to a police central station, where she learns from the rude Sgt. Cohen that the station was decommissioned and will be closed. He shows the precinct and tells her that she will stay alone waiting for a Hazmat team that will collect hazardous evidence and gives his phone number to her. In the beginning of her shift, a beggar gives some trouble to her, and she locks the man in a cell. She receives a distress call from a woman, but she is unable to locate the whereabouts and communicate to the new central station. Then she asks the prostitute Marigold to leave the area in front of the station and the woman tells Jess that John Michael Paymon, who the leader of a cult that worships the devil and responsible for the murder of her father, and his sisters Kitty Paymon and Dorthea Paymon, committed suicide in that station. Strange things happen in the precinct scaring Jess, but when she receives another phone call from the girl, she learns her name, Monica, and the location where she is. Jess calls the central station, and the detective tells her that Monica was killed one year ago, and it is probably a prank from the Paymon family. Further he tells her why the station was closed. Her night in hell has just begun.
