Romantic feelings resurface between Olshansky and his high school girlfriend as he reconnects with her while trying to help her schizophrenic sister.

While Mike identifies the man who shot Marcellus as someone who escaped from a drug dealer take-down long ago, a second attempt on Marcellus's life points to the possibility of two different shooters; forced to hide out from some bad guys, Jamie temporarily moves in with Mike, and Liz teaches him how to be a good neighbor.

While Mike is more than willing to assist Jamie in turning a teenage friend away from prostitution, Liz is much less sympathetic to her plight until Jamie convinces her that the privileged upbringing he and the girl shared is no protection against pain; continuing to mentor Cal, Marcellus strikes a bargain with a loan shark to arrest his competition on the street in exchange for his releasing Cal from his crew; Mike walks on eggshells in the face of Liz's anger; after Liz manages to get Cal out of the shelter and into a foster home, Deborah agrees to let him stay at the Washington house until his foster placement goes through even though things are very much strained between her and Marcellus; Mike, Marcellus and Liz use their individual talents to get Jamie's friend out of the hands of her pimp and into the arms of her parents.

Mike uncovers an illicit adoption ring trafficking in stolen babies when he grudgingly agrees to help one of Liz's clients, a former addict who's turned her life around, in the search for her missing child; Marcellus calls an end to it when he realizes that his obsession over the new man in Deborah's life has gone too far.
