Navigating the complex labyrinth that is high school - friends, relationships, classes, and teachers - is challenging enough, but four friends find themselves grappling with the question of what's more important: Loyalty or self-preservation? When Rock, Lilly, Damon, and Tom have a substitute teacher following the passing of their previous teacher, they react like normal high school students - joking, goofing off, and playing around until the new teacher displays a hidden "talent." After students misbehave, she runs her long nails down the chalkboard, causing immense suffering amongst the teens. When a few suspicious incidents occur, Rock theorizes that their new teacher, Bella Christianson, has some mysterious unknown ability that is plaguing them.
After Tom, one of Rock's friends, gets sick under mysterious circumstances, it's up to Rock, his girlfriend Lilly, and his friend Damon, to find out what is going on with the new, young attractive sub, Ms. Christianson. There's something about her that Rock finds uncontrollably hot, but at the same time, there's something off about her. And to make matters worse, people keep turning up dead. Nonetheless, after being seduced, Rock begins a forbidden love affair with his teacher, all the while observing her strange behaviors. But how long can it last? Will Rock and his friends be able to survive their encounters with their dangerous teacher?
