Hit Team

Original title: 重装警察

An undercover cop badly injured in a raid is blamed for the raid's failure and thrown out of the police department. His injuries result in his being paralyzed form the waist down, and doctors tell him that if he doesn't have an operation within a few months, the paralysis will be permanent. His friends in the police department decide that, since the underworld was responsible for their friend's injuries, the money for the operation should come from them, and they set out to get it.
