With his ticket in hand, Man Tsai is excitedly waiting for his eighteenth birthday, which he is going to celebrate by watching a category Ill movie. Meanwhile, he looks back to his "not-yet-adult" days: taking part in Talent Kid Contest; 
the fiasco at getting into the Macau casino with his cousin; 
the date with a girl knowing from a "line party" 
And recently, a close friend was caught by the police for selling CD duplicates...

Standing in front of the cinema entrance, Man Tsai becomes aware of the relation between "freedom" and "responsibility".
