Open 24 Hours (2018)

A young girl gets a graveyard shift at a gas station situated in the middle of nowhere. She tells her boss that she has done time in prison for burning her serial-killer boyfriend, who survived the burns but is now incarcerated. However, she doesn't mention to the boss or her parole officer the paranoid delusions that have started to plague her. Things go from weird to downright complicated on her very first night on the graveyard shift as the line between illusion and reality blurs.
