While pulling an April Fools' Day prank on a nerdy classmate named Melvin, a group of high school friends (Missy, DeAnna, Eva, Diego, Malik, and Marlin) accidentally kill him when Marlin hits Melvin with a football, causing him to fall on and he is impaled by a piece of rebar as a result. Panicking, the group drag Melvin's body into a wooded area, and stage it to look like he was the victim of a random gang-related attack. Exactly one year later, DeAnna is stabbed to death by a hooded figure while interning at a hospital. After murdering DeAnna, the killer writes "April Fools" on a wall with her blood. Now the group thinks a reincarnated Melvin has something to do with the murder.
