Shanbei City is a remote town surrounded by mountains.
Female student Li Meng lives in a large dormitory off campus and leads an ordinary college life - until the day after school.
On her way down the mountain, she spotted a statue with an angry look on her face. It wasn't Guanyin, or any other Buddha she knew. It calls itself "Karma" and claims to be the real God who saves the world. His good intention is to get rid of the bad people in the world.
Li Meng saw with his own eyes that a gentle man in a yellow jacket and a girl in black with long hair were hanged from a tree.
She ran away. But she didn't know that the purple mark on her leg had created an unbreakable connection between her and this ancient statue.
Concept: Can good and evil be quantified? Is the degree to which a person is disliked equivalent to his sin?
