   Summary

   In a post-apocalyptic world, and after spending years fighting the tyrannical Krang, Mikey gets an ominous warning. What happens when they die? Will the Hamto legacy end with them? Grappling with their morality, the four brothers need to come up with a solution. Donnie has an ethically questionable plan. A disgusting, gore-filled, impossible plan. And Leo is 100% on board.

   Some things cannot be UNDONE.
