Michelangelo is a ninja again, albeit 17 years out of practice, so he juggles memories of old lessons in addition to his great personal angst, compounded when he encounters a cat that looks exactly like his old cat Klunk. Back at the apartment, Shadow and Renoir are in a nasty condition as the Jones and Hamato families ready a plan to save Mikey and Davianna from danger. But for the plan to work, Renoir needs to come along again to help them track down the Foot. Meanwhile, Davianna believes Shadow has been murdered, and the mysterious Foot Elite keeping her hostage informs her she won't be surviving this in any event. Mikey prepares to rescue Davianna and his niece Shadow, but Davianna informs him that Shadow has already been killed.
