On his 70th birthday, Mr. Kim Bong-suh receives a car as a gift and takes a driving license test. He is sincere enough to not pick random answers in those multiple-choice questions and tries to solve the questions to which he might know the answers. When you try to solve a test, it is the way of nature that you are put to the test. The mind of an old man in his 70s that even a 17-year-old can understand. (JANG Youn-sun)
