The Lift(2020)

DON'T GO IN THE LIFT ALONE!

University student Trang's friend suddenly goes missing after she was last seen playing a ritual game in an elevator. She and her cousin investigate the place where the girl vanished, and get obsessively invested with what might be a door to a terrifying dark world. The exploration gets even darker when they commence a thrilling cat-and-mouse game with someone - or something - that's out to get them.
