Karma is just another lazy and sarcastic teen with some anger issues if you know what buttons to press. He lives with his mother who is always working. There is one thing wrong with Karma, he has no sense of fear. Ever since he can remember, he has never been afraid in his entire life.
One day his house is a target for a murderer. When Karma finds the killer in his house, he doesn't even question it and goes back to whatever he was doing. The killer, confused and wanted to know why he didn't react like everyone else holds off killing Karma to find out why. He finds out he doesn't even want to kill him, instead he finds Karma interesting. However, Karma just finds him plain annoying.
What happened to Karma and what does the Murder think of this? Will he teach him a different kind of fear?
