Yilan youth Lin Yuxin (Eddie Peng) once spent a happy youth in the gymnastics team. At that time, the lively and active little Ashin had outstanding talents and was highly valued by the coach. However, as he grew older, Ashin's congenitally long and short legs made it difficult for him to improve his gymnastics level. He could not resist the request of his mother who ran a fruit shop, so he had to stop training to sell fruit. He and his friend Cai Pu (played by Ke Yulun) fought with various people on the streets every day, and thus became friends with the telephone secretary 559 (played by Lin Chenxi) who delivered the killing notice for him. In order to stand up for the stall of his former gymnastics teammate, Ashin and Cai Pu offended Mu Gua (played by Chen Handian), the son of a gangster boss, and repeatedly embarrassed Mu Gua. Mu Gua induced Cai Pu to take drugs and set a trap for Ashin, but was seriously injured by Cai Pu. Ashin and Cai Pu had to go to Taipei to escape the disaster. The gymnastics dream of their youth has become blurred at this time...
