Lily, an asthmatic mid 20s Muslim doctor and her fiancée Kit go on one last holiday with their med school friends before they move abroad. Lily also meets Kit's over-protective younger sister, Rachel, which goes okay, but Rachael is suspicious of Lily's motivation. She has never given her brother's girlfriends a chance, Lily is no different. They pick up a hitchhiker, Marc, on the way to Saint Joseph's guesthouse. Using the legend of the hanged girl, they set up a prank to make Lily think she's the next victim of an evil cult. Terrified at first, once she works out it's a joke, she seems okay with it. But she is not and starts having vivid nightmares and flashbacks about the hanged girl, so real that she starts to wonder if they are real. Lily hides this and the holiday seems to be going well, except Rachel gets more and more vindictive. Lily fights back, and this triggers Rachel to attack harder. As day becomes night, things start to get weird, as the friends struggle to control their emotions, something is not right. Lily's research says it may be supernatural, the ghost of the hanged girl. Lily tries to persuade them that they must escape, but it's too late. As their fears and desires start to control their actions, they turn on each other as death stalks them. In a final twist, nothing is what it seems.
