Luz (Light) a beautiful European aristocrat finds herself estranged from her wealthy family and hooked on drugs in Los Angeles. Luz meets a postman who changes her way of thinking.

A group of friends return to the institute after the summer. Everything seems calm, and after their old confrontations, they seem more united than ever. But a strange event upsets the apparent balance: someone has stolen the statue of the institute's founder, and Borja, despite having totally changed his life, is accused and expelled because of his troubled past. But this is only the beginning. There are strange bullying cases, and the suspicion that not everything is what it seems leads some of the boys to distrust everything and everyone. A race against time begins with nobody knowing. Appearances can be deceiving, and if the boys are unable to truly trust one another, a danger greater than any other will strain the institute with disgrace.
