On a cold, blood-soaked Sunday in New Jersey, Wade Wilson—aka Deadpool—is dragged into a deadly church massacre when a mysterious cult of mutant-hating zealots targets a young girl with uncontrollable powers. With a katana in one hand and a churro in the other, Deadpool must slaughter his way through corrupt priests, cybernetic mercs, and an excommunicated assassin-nun with a grudge, all while babysitting the human nuke who might just end the world—or save it.
