Yesterday my father and mother took me to see the movie Crazy Primitive Man. The movie is about the six members of the primitive family living in the cave. They all listen to their father very much. Only Xiaoyi doesn't like darkness and doesn't like to stay in the cave. One day the earth began to crack, and their cave collapsed. They had no cave to live in, so they had to find a new home.
During the journey, they met a boy named Gai. He was smart and intelligent. He came up with many regulations to help the primitive family. They avoided many difficulties and finally found a new home.
