The film begins with Snapchat personality Andrea Russett announcing to her followers that her cousin Taylor was flying to visit her for the weekend. This coincides with a Twitter request she had received from Sean O'Donnell, who wants Andrea to visit a supposedly haunted cabin called "Sickhouse". Once Taylor arrives the two women bond and Andrea teaches her cousin to use her Snapchat, which Taylor uses to publish a video of Andrea sleeping, the first of many videos posted by Taylor throughout the film.
