The Hamiltons seem to be the picture-perfect American family. They are hardworking community members; giving to their local charities, attending town hall meetings and always respectful of their neighbors...except for the fact that they usually end up killing them.
When an April Fool's Day prank turns deadly, Desiree Cartier, her brother Blaine, and five of their friends all become the targets of a twisted kill who begins hunting them down one by one.
