After the events in "SubZero" Mr. Freeze has been forced to be bound to a new robotic body. His wife Nora has been revived, but believing him dead, she has remarried and left Gotham. If Freeze can't have a life of happiness, nobody can, so he begins lashing out at the city by destroying what people care about so they can feel the same pain he feels.

In an effort to further distance himself from Batman, Nightwing tries to go it alone to stop a smuggling ring and gets unexpected help from the seductive Catwoman, who attempts a somewhat sensual relationship with him.
