Andy Sipowicz (Dennis Franz) tries to persuade the nervous Officer Mike Shannon (James McBride) to provide the evidence needed to clear Andy's partner, John Clark Jr. (Mark-Paul Gosselaar), of a trumped-up drug charge. Meanwhile, Clark Sr.'s (Joe Spano) drinking problem gets worse, a bad cop gets his comeuppance, and the 15th investigates the murder of a community activist who worked with female gang members. ~ Hal Erickson, Rovi
