Carlos, a 21-year-old Madrilleno student, likes to be provocative and to break the rules. It is summertime, and he lives mostly by night. He and his mates meet at the Kronen. As he fails to understand the society he lives in, Carlos fights it in his own way; by rejecting all standards and principles, by praising hedonism, by refusing to get emotionally involved in a relationship. Sex, drugs, alcohol and music are his only allies in a search for his own identity. But when he discovers it, he has gone too far.
