It’s a true story and it’s about a girl who goes on a college trip with her friends to some place with a beach, and she meets a guy in a bar/pub and they’re doing body shots off each other and some random stuff and then she goes missing and her college trip people (her friends and professors) have to leave the place without her because they couldn’t find her and the last scene or somewhere in the end it’s show that she’s unconscious/dead and on a boat. I’m not sure but I think the guy who she met tried to rape her and sell her off as a prostitute
