Medavoy and his new partner, Detective Baldwin Jones, join Sipowicz and Sorenson as they investigate the peculiar disappearance of two young boys on a trail that leads them to a racist, deranged Russian man. But Sipowicz is a bit skeptical of Jones, the new guy, and doesn't try to hide it. Danny treats Mary Franco dismissively and seems more interested in Diane. Diane and Jill investigate a girl who died as a drug mule and get a suspect to incriminate himself.

Sipowicz and Sorenson reopen an unsolved case involving a missing little girl when a small body is discovered buried in a wall. Andy offers emotional support when a troubled Sorenson is plagued by persistent nightmares but it's Diane whom he ultimately confides in. Meanwhile, Medavoy and Jones resort to a bit of theatrics when their slam-dunk shooting case is hampered by a pet owner who refuses to let them retrieve a bullet from her dog's nose that's needed as evidence.
