His mother thinks Ashin's sport won't amount to anything and asks the coach to take him off the team. Disheartened, the young man gives up gymnastics and starts to hang out with the wrong crowd.

Things take a turn for the worse when Ashin's best friend, Pickle, gets addicted to drugs. Soon the two have a problem with the son of a local kingpin and are forced to flee to Taipei.
