Sarah Chalke (“Scrubs”) Guest-Stars Backstrom comes home to find Dante Trippi, Valentine’s abuser, murdered on his doorstep. Worried that Valentine could be next, the S.C.U.’s investigation leads Backstrom to a ring of counterfeit wine smugglers, a corrupt river patrol cop and a Club of Portland government official. Meanwhile, Valentine’s inability to tell the truth makes it harder for the team to catch the killer and Amy (guest star Sarah Chalke) has a new boyfriend, of whom Backstrom is not fond.
