There is a painting teacher who is a smoker. He complains to one of the student's mother about her son, who is silent and draws meaningless lines instead of painting. The teacher says that it is better to take him to another class where he may find his talent.

The mother says maybe his silence is because of his father's death from lung cancer. She decides to take her son home. So the boy completes his painting very fast and when they are going out, the painting teacher realizes that the boy's painting is about a dreadful monster which comes from some lines which are the lines of cigarette's smoke and all of them are 4 pieces of a puzzle.
