When Greer is seriously hurt by phony cops (one of these a drug dealer whom Greer had previously apprehended), and four suitcases of heroin belonging to a crime syndicate are stolen, Sgt. Ed Lassiter leads the Squad on their most challenging assignment ever, looking at every possible connection. 

The Squad investigates when a youth joins a motorcycle gang, plots a fake payroll robbery of his father's company and learns the other gang members are playing it for real.
