Valens partners with Rush to locate her abducted, drug-addicted sister. Meanwhile, Jeffries tries to bring justice to the case of a murdered teenaged girl that has haunted him for 17 years. The team investigates the 1989 case of a prom queen, killed by a hit- and-run after her prom. Rush’s sister suddenly resurfaces.
We pick up where we left off in episode 21 with Rush entering a trashed motel room hoping to find her sister Christina who’s been missing. Rush’s service weapon is taken after she’s hit and knocked unconscious. She enlist the help of Valens to help her find Christina, but not before they stop at Rush’s house to pick up her unregistered gun Saccardo gave to her. They track down the unsavory doctor who prescribed Christina Oxycodone and uncover a string of pharmacies who have been supplying drugs to addicts in exchange for cash. Christina and her thug of a boyfriend, Cliff, were frequents at some of these pharmacies. In the end Rush and Valens track down a badly beaten Christina in a Jersey apartment but not before Cliff shows up. Rush does to Cliff what he did to Christina. It turns out Christina has baby and was reaching out to Rush in an attempt to get her life back in order. New evidence on a young girl’s murder that’s been haunting Jeffries for the past 17 years gives him reason to open up the case. Wanda Johnson, a smart and vibrant teenager was shot and dumped and her murderer was never found. Shocking new evidence reveals that an eye witness saw her in Mercury Sable that we learn to be owned by Deputy Commissioner Patrick Doherty. It turns out that Doherty’s son, Matt, and his buddy Ronnie offered Wanda a ride home from school back in 83. They made a detour and decided to settle a score with a drug dealer that ripped them off. Matt pulls his father’s .38 out of the glove compartment spooking Ronnie who yells at him to put it back. Ronnie tries to take the gun away from Matt and it accidentally goes off killing Wanda. In a panic they dump the body in the Badlands. Patrick Doherty covered for his son all these years.
