Senior Inspector Don Lee relies heavily on the information provided by stool pigeons in his job. Barbarian is a painstakingly meticulous armed robber. Don needs an informant to infiltrate his gang and recruits street-racer Guy. Guy delivers, but Don is unable to effectively act on the information until the final moment. Since Barbarian has not left any evidence, Don is pressured to convince Guy to become a witness for the prosecution and promises him a new identity in another country; Guy barely escapes with his life. A disillusioned Don is left wondering if his quest for justice is worth the price that often has to be paid.
