After spending one last day in HK, Lam Ming Che intentionally gets himself arrested and put in juvenille prison, in order to find his friend Chan, arrested on a previous night of adventure. In prison, he discovers and becomes part of a whole new culture and economy, where wealth is measured in candy and small freedoms mean everything. This is an interesting story that is told amazingly well (in both direction/writing and acting). Highly recommended for anyone who likes a good simple tale.
