There are three rules for the game of "Wolf Eats Sheep": one is to avoid suspicion; two is to deceive friends; three is to eliminate friends. Owen Matthews (Julian Morris) transferred to West Lake Middle School, where he met new friends, Daozhe (Lindy Booth), impatient Tom (Jerde Padalecki) and others. These people are members of a "Lie Club" and they often play a game of "Wolf Eats Sheep". This game emphasizes disguise and deception. One day, a young woman was killed near the school, and the police had no clues. The "Lie Club" decided to turn this story into a "campus ghost story". They posted fake news on the Internet, fabricated a perverted murderer nicknamed "Evil Wolf", and said that "the next victim will be a classmate in the school." The members of the "Lie Club" were deeply immersed in the pleasure of making up lies, but they didn't expect the lies to come true! The classmates suffered misfortunes one by one. Who is the "Evil Wolf"?
