Hong Kong cop Jack Chan (Eason Chan) has no passion for his job. After seven years of patrolling, Chan has yet to use his weapon in the line of duty. Then, he lands an idealistic new colleague (Joey Yung) who seems more interested in rescuing stray cats than, well, slacking. But things change when Chan begins to see the light after a group of smitten high school girls ask him to help them in Judo class at school. James Yuen directs.
