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.

T.C. is outraged when ""The Sandman"", a hitman responsible for the murders of a police informant and an innocent bystander, is released from prison.Against the orders of DEA agent INSPECTOR ENRIGHT (from the episode ""Black Pearl""), T.C. trails the Sandman on his own, hoping to catch him committing another crime. Enright finally arrests T.C. for obstruction of justice. Neither knows that Sandman plans to use T.C. in exacting revenge on the three drug runners who made him take the fall for the informant's murder, and in such a way that he -- the Sandman -- won't even have to pull the trigger...
