While watching a news story about Larry Trask, son of the late Sentinel inventor Bolivar Trask, Iceman and Beast are attacked by a new model Sentinel. As the news story plays on and Trask reveals that he has rebuilt and redesigned his father’s robots with new weapons and that they can be pre-programmed with orders or operated by a remote control helmet, Bobby and Hank fight their attacker. While Bobby is captured by the Sentinel, Beast is forced to flee the scene when he realizes that he is outclassed against his Sentinel attacker.
While in Egypt, Cyclops, Marvel Girl and Angel take a break from their search for Scott's brother Alex to listen to answer a radio call from Hank. Hank explains to the group of Larry Trask and his Sentinels and Bobby's subsequent capture, but has to cut the transmission short to focus on avoiding capture himself. Warren defies Cyclops' orders and decides to fly back to the United States on his own to help his friends against the Sentinel menace.
While at the secret hideout of Larry Trask, Larry talks to Justice Robert Chalmers who expresses concerns about the "proof" Larry has provided that all mutants are a menace and to tell him that the public is not entirely sold on the idea. Larry agrees to let the press talk to the captured X-Man once he is rendered harmless. When Bobby arrives at the Sentinel base, Larry has him treated to a chemical steam bath that nullifies his ice powers for four hours. When Bobby attempts to attack Trask, a Sentinel stops him and Larry reveals that a hidden video camera had recorded the attempted attack which he intends to use as proof of the "mutant menace" that he is trying to sell, and vows to get revenge on the X-Men for his father’s death.
Taken to a holding cell, Iceman finds both Lorna and Alex there. He learns from Alex that Trask had designed him a special suit to control and regulate his powers and given him the codename Havok. Alex then tells Bobby that he was given all this in return for making a deal with Trask so that Lorna would be left alone. However, Bobby brands Alex a coward before hearing this, and as he's being told a Sentinel enters the room and grabs Lorna. Realizing that Trask's word was meaningless he unleashes a powerful plasma blast that destroys the Sentinel. Entering the room with another Sentinel, Larry then uses a device that nullifies Alex's powers. This horrifies Alex as this will reawaken the mutant abilities of Professor Abdol allowing him to transform into the Living Monolith once more.
While in Egypt Ahmet Abdol is meeting with government officials about his altercation with the X-Men earlier when he suddenly feels his powers returning to him. However before he can completely transform into the Living Monolith once more, two Sentinels arrive on the scene and douse Abdol with a special adhesive that blocks him from the cosmic rays that feed his power, neutralizing his threat and allowing for an easy capture.
Trask sends out an army of Sentinels to capture all of the remaining mutants in the world, and a pair captures Angel with ease. This capture is watched through the horrified eyes of Scott and Jean who witness this capture while looking out the window of the airplane they are using to fly back to the States. While at a secret hide out, Mesmero and Magneto are attacked by another Sentinel. When Magneto attempts to stop the robot, it blasts him revealing that the being that Mesmero has been working for all these months was not the real Magneto, but a robot, and he is easily captured by the Sentinels.
