Stone and Sanchez, dealing with the fallout from their personal attraction, are assigned with Fitch to investigate the murder of successful executive Abigail James from Detroit's "Tech Town." Is this a case of corporate competition gone haywire or the result of a messy love triangle? At the same time, Longford and Washington need to piece together the back story of another fresh murder case -- the lifeless body of a young drug dealer, "Toucan," is discovered in a trash bin, but is it strictly street business or pure personal passion? Meanwhile, Mahajan must search the city for a crucial eyewitness who failed to show in court to help convict a vicious skinhead of murder, and without him the killer may walk.
