A compilation of episodes from the lives of several of the amateur actors' (who are 'bad teens' and the homeless of Seoul) own experiences, this film sheds light on the dark side of Korean society. Feeling alienated and persecuted, they wonder about and come into conflict with the 'good people' who persist in trying to reform them. They have their own reason for remaining as they are and resist attempts to reform them: they cannot change simply because they are bad.
