Having returned to New York following his adventure with Ka-Zar in England, Daredevil returns to his apartment and resumes his guise as Matt Murdock, just as Foggy and Karen have arrived. Foggy has almost fainted, a remission to the injuries he sustained from the Ox.

Meanwhile, in the state prison, the Ox himself has teamed with his cell mate Karl Stragg, who offers to use his scientific know-how to give Ox the intelligence he's always wanted in exchange for busting them out of prison. However, when they break out of prison and escape to Stagg's lab, the device Stagg uses instead switches their body -- Stragg's plot all along -- and the now super-strong Stragg goes on a rampage.

It's during this rampage that Stragg is spotted by Karen Page, who recognizes him as the Ox, Daredevil happens to swing by and see the behemoth and battle him, however the Ox easily defeats DD and places an extra Ox costume on DD so that when the police arrive, they think that Daredevil is masquerading as the Ox to get away with crime and so lock him up.

Meanwhile, Stagg takes Karen back to his lab where the original Ox (now in Stagg's body) knocks Stragg out and helps Karen escape. The Ox now goes on a rampage, leading the police to realize they have the wrong person and set DD free to deal with the menace. Their fight takes them to the top of a building where the fighting mad Ox accidentally runs off the edge of the building and plummets to his death.

After the battle, Daredevil returns to his civilian guise and meets with Karen and Foggy to find that Foggy will be okay, Karen wonders what happened to the man who saved her from the Ox. The story closes with the Ox, feeling better and a little smarter in his new body, decides to return to prison to finish his sentence.
