Taskmaster steals a digital file containing the secret identities of every superhero who works with S.H.I.E.L.D., including those of Spider-Man and his teammates. Frustrated by a recent string of misfortune and his demanding S.H.I.E.L.D. training schedule, Spider-Man accompanies Deadpool (an absent-minded mercenary who once trained with S.H.I.E.L.D.) on his mission to retrieve the file. Spider-Man soon starts to realize Deadpool is not a true hero.
