On the streets of Chengdu in Sichuan Province we meet twelve-year-old Hu Jian and his friends, stealing to pay for drugs and addicted to heroin. The director’s hidden camera reveals the structure of an underworld exploiting children for cash and its back-scratching alliance with the police. She struggles to get the kids to Beijing to stop them from taking drugs and tries asking an orphanage to protect them, but ends up with her life threatened by the police and the underworld. The title was taken from the 350-yuan bail (equivalent to 5,000 yen) for the release of a minor arrested by the police.
