A young Latino man is shot to death and no one, including his pregnant girlfriend, wants to talk about it. Bobby works with a gang member's childhood friend, now a straight-arrow former MP who is on the background check list to join the NYPD, and they put the case together. A high-profile case involving the murder of an auto-repair shop owner who was a huge booster for the police has unlikely lead detectives in Greg and James. However, Greg finds an offbeat way to solve the killing. Diane and Jill catch a shaken-baby case that turns into a homicide; they find the baby's parents disgusting and sympathize with her caregiver as the sad story is revealed. Greg drinks too much wine and tells some stupid jokes, but otherwise enjoys his dinner with Abby and her partner, and Diane is inspired by Jerry Maguire into having a new answer to Bobby's marriage proposal.
