At a military hospital in Beijing, a doctor pumps 'calming fluid' into a patient. The patients here are not victims of war - they're internet addicts, many of whom became violent after getting caught up in virtual worlds. "For us teenagers, the pressures from school are just too much," explains Qing, committed after he tried to stab a classmate. "I had no way to solve my problems and no place to release myself." Dr Tao Ran claims internet addiction is a serious disease which needs proper treatment. "Their minds merge between the real world and the on-line world." But his clinic can only treat a few. For the problem to be solved, change needs to happen across society.
