The innocent view of "I am the King of the Castle" is quite different from that of ordinary children's movies. It depicts a little boy who follows his mother to a country house as a babysitter. The boss's son thinks of various ways to torture the boy from time to time because of the loss of his mother and his desire to attract attention. Especially after discovering that the father is interested in the babysitter, it gets worse. When the mother found her son's humiliation, she angrily chose to leave, but the considerate little boy knew that the widowed mother also fell in love with the male master, so he took the initiative to fulfill his mother. But on the day the new family took pictures, the boy ran away without warning, leaving a brand new dress on the shore, and he chose the sea. How did the young master who shouted his name know that the evil deeds distorted by the feelings he refused to express directly had deprived him of the only life that could grow up with him! In addition to the unimaginable opposite play between the two boys, the little boy danced with his mother in the pub, which was surprisingly beautiful.
