A deadly new form of heroin hits the streets of Santa Monica, sending the Bike Patrol into overtime as all hell breaks loose. During the investigation, T.C. falls under the seductive spell of an undercover DEA agent who's investigating one of the drug distributors but has become an addict herself.

Victor is ordered to attend requalifying training on the bike, and much to his horror, his instructor is HANS REY, a former instructor who made his life miserable the first time around. The two engage in a one-upmanship contest, judged by Chris.
