Girl goes to college and meets a group of friends she doesn’t know that they are trying to do satanic rituals on her they start by giving her a tea to drink which makes her lose weight like crazy and then a facial mask to give her clear skin but the goal of the people is to make her perfect so that the other girl can take over her body and posses her in the end she ends up dying and her older sister tries to go to the college to investigate it and the friends act like they didn’t know who her sister was. I wanna say this is like a low budget movie from 2015 its english.
