Their plan works with two of the girls but the third, Mary Banner (Lillith Fields), tries to escape. The football captain chases her into a storage room and punches her, knocking her out. Unable to revive her nor able to hear her heartbeat, he believes Mary to be dead. Panicking, he locks her body in an old trunk. Thirty five years later, in 2004, this story is told among three school girls during a sleep over. One of them, Samantha (Kate Mara), had written an article in the school paper critical of football players' academic achievements and subsequently she, her friends, and her brother David (Robert Vito) are treated as outcasts by the rest of the school. They also jokingly conjure up Bloody Mary and the next morning all three are gone. After having been missing for one day, they reappear, waking up in an old deserted mill, with no knowledge of how they got there. While most suspect a hoax on the girls' part, Samantha and David suspects that it is a prank by football players. While Samantha is haunted by visions of a dead girl bleeding from her head, several pupils die under mysterious circumstances resembling urban legends; for example, football player Roger (Brandon Sacks) burns in a sunbed, Heather (Audra Lea Keener), girlfriend to football captain Buck (Michael Gregory Coe), has spiders erupting from a swelling on her cheek, driving her to cut her face with a mirror, and football player, Tom (Nate Herd), is electrocuted while urinating on an old electrical fence, his ring finger being bitten or cut off. Buck blames these deaths on the Owens siblings. Before her death, Heather made up with Samantha and tried to tell her that this happened before. In her homework, Samantha finds notes sent to Heather...
