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.

Later, Eva is stabbed in a locker room after dance practice by the same hooded assailant, who once again writes "April Fools" on a wall in blood.

Unaware of Eva's death, Missy goes to the high school's Spring Jam, despite being unnerved by surveillance footage of DeAnna's murder, accidentally left in her room by her detective father.

At the Spring Jam, Missy recognizes the attending killer from the surveillance footage, and looks for help from Malik after witnessing Diego and a teacher be murdered.

This is a perfect storm of incompetence on all fronts: acting, writing, direction, editing, continuity, special effects, and basic human decency.
