Mike Kellerman's new vocation is private investigation, where the majority of the work involves catching cheating spouses. Falsone and Stivers catch a case where a newborn baby's body is found buried behind a motel. A young couple had checked into the room where the baby was delivered. The room was paid for using the girl's credit card. When they locate the girl (Debbie at home with her parents), she collapses and is brought to the hospital. The boy, Craig, is also located. Both say that the baby was stillborn; however, the autopsy reveals that the baby took a breath after it was born, so the death is ruled a homicide. Falsone notes that of the two, only the boy Craig seems to show any compassion for the baby. Kellerman meets Sheppard for a beer and tries to ask her about Falsone's baby case, later he asks around the squad room. Kellerman is hired to conduct his own investigation by the girl's defense team. Gee demands that Falsone and Stivers find convicting evidence before Kellerman
