In a story about need to belong, Joe, Bill's son, is out on the edge and alone — an addict, and Bill knows that the only person who can save him is his dad. That means getting Tony Pelucci to turn his back on the only culture and support system where he belongs, his criminal mates network. Bill and Charlie investigate two colleagues when an accusation of rape is lodged against two police officers while Maxine helps Joe go through withdrawal.
