They only meant to scare him.  They never intended to KILL...

Mr. Griffin is the strictest teacher at Del Norte High, with a penchant for endless projects and humiliating his students. Even straight-A student Susan can't believe how mean he is to the charismatic Mark Kinney. So when her crush asks Susan to help a group of students teach a lesson of their own, she goes along. After all, it's a harmless prank, right?

But things don't go according to plan. When one "accident" leads to another, people begin to die. Susan and her friends must face the awful truth: one of them is a killer.
