Two years after the events of the first film, Wade Wilson/Deadpool (Ryan Reynolds) fails to kill one of his targets, who then kills his wife Vanessa (Morena Baccarin), whereupon he gets his revenge by grabbing the guy and stepping in front of a bus. He attempts to commit suicide by blowing himself to pieces, but all his pieces are still alive and Colossus (Stefan Kpicic) puts him back together.
Recovering at the X-Men mansion, Wade finally agrees to join the X-Men, complaining that the studio still will not spring for more than two X-Men; meanwhile, the entire cast of an X-Men movie quietly shut the door behind him. He, Colossus, and Negatonic (Brianna Hildebrand) rescue an unstable young mutant named Russel Collins or Firefist (Julian Dennison), who has pyrokinetic powers, from a Mutant Re-education Centre, where he had been abused. Wade and Collins are arrested for killing an abusive staff-member and are taken to the Icebox, an isolated prison for mutants. A cybernetic soldier from the future, Cable (Josh Brolin), whose family will be murdered by Collins some years from now, travels back in time to kill the boy before he becomes a murderer. Josh Brolin plays it absolutely straight and is one of the funniest things in the movie.
Cable breaks into the Icebox to gain access to Firefist. Deadpool defends the boy but can’t break him out of prison. Deadpool organizes a motley team called X-Force to free him from a prison-transfer convoy, but everyone dies stupidly in the first few minutes except Deadpool and Domino (Zazie Beetz) whose mutant power is that she is incredibly lucky. In the process of freeing Firefist, Juggernaut (voiced by Ryan Reynolds) is also set free and he becomes Firefist’s protector as the boy sets out for revenge. Frustrated by all the shenanigans, Cable agrees not to kill Firefist if Deadpool can talk him out of the first murder—that of the abusive orphanage director—that sets him on his destructive course.
If anything, Deadpool 2 reveals a darker and more offensive humour than the first movie. The battle scenes are every bit as exciting, complex, and ridiculous—particularly the absurd lucky co-incidences that protect Domino from the natural results of her insane bravery. Deadpool is beaten, shot, stabbed, drowned, blown up, ripped to pieces and makes stupid jokes, movie references, and nasty comments throughout. The music during every scene is wildly inappropriate. The opening credits are a Pythonesque parody of the James Bond credits, and the mid-end-credit extras involve Deadpool using Cable’s time-travel device to go back and save actor Ryan Reynolds from bad acting-choices. Some might think Deadpool 2 is one of them, but I found it immensely entertaining and only slightly tedious at times.
