Set a year after Deadpool 2, 3 follows the Merc With A Mouth as he sets out to save US Senators Joseph MacTaggert and Hank McCoy from the mutant villain team known as the Acolytes. Oh, and they've captured MacTaggert's son, Kevin, aka Proteus, for good measure.
To build help for his mission - for better or worse - Wilson assembles two different tier teams consisting of weird, almost as crazy, and otherwise B to C list but effective superheroes also from the comics: The Mercs For Money and the Chimichanga Table.
