Matt decides to take a cruise to get his mind off of Karen. After his cruise ship is boarded by pirates, DD is taken to the Savage Land by the Plunderer. Ka-Zar attacks the Plunderer for trespassing on his domain and saves Daredevil's life as his costume reminds the savage lord of his encounter with the X-Men.
DD and Ka-Zar battle the Plunderer as the villain regales them with his origin and the origin of his savage brother. The Plunderer is after half of a neclace that his father gave the two brothers that will open a vault to a substance that destroys all weaponry. Everybody gets greedy and even the pirates and the butler (Feepers) vie for the halves of the medallion.
The Plunderer gets his hands on Ka-Zar's half of their father's medallion and uses the mytical Plunder-Stone to start taking over the world. DD gets in the way and helps take the would be world conquorer down. Foggy and Karen show up in England to defend Ka-Zar against trumped up charges his brother brought against him.
The Ox is convinced by his cellmate, Dr. Karl Stragg, that if the two can escape, the good doctor will make Ox smarter. Stragg double-crosses the Ox and switches bodies with the brute. DD tracks down the new and improved Ox only to defeat him permanently.
A burly costume store owner decides it is really the clothes that make the man and begins his career as the Gladiator. Foggy gets a Daredevil costume from Melvin who talks the tubby lawyer into setting up a staged super fight to impress Karen. Thinking his fight with Foggy will draw out the real DD, Gladiator goes after him for real and Matt has to take a hand in rescuing his friend. In the night and the fog, everyone assumes it is Foggy as Daredevil that beat the Gladiator back.
The Masked Marauder busts Gladiator out of jail and the two fight over the privilege of taking Foggy Nelson, a.k.a. Daredevil, down. Everything is going as planned until the real DD shows up to save Foggy's chubby butt.
