Double trouble for Action Man! Evil Professor Gangrene steals an atom-freezing device. Action Man tracks him to the English Channel, where Gangrene freezes the water, trapping Action Man under the ice. Meanwhile, Doctor X steals radioactive waste from a nuclear plant, using the frozen channel as an escape route. A battle between Action Force and the skullmen commences in the icy channel. Can Action Man and the Action Force prevent the explosive-rigged toxic waste from blowing up and contaminating the world's oceans?
The Action Force get an “Action Alert” that Dr. X and Gangrene have stolen a device called the “MPS” that can “stop all molecular movement.” They say it’s like “What happens to Atoms at absolute zero.” While doing so, Gangrene fires a missle that blows up a piece of the Big Ben. Upon learning this, Action Man and his Action Force take off from their satellite base and head off to find him. Also, before leaving, Action Man has a flash of memory from his childhood.
Apparently, he wasn’t very popular. He sits at a bench while the other kids play soccer. The ball rolls to him and he thinks they want to play with him, but another kid comes and kicks the ball back so little Action Man just sits right back down in silence. On their way to the mission, they receive another “Action Alert” telling them that Dr. X has now stolen three trucks filled with plutonium from a Nuclear power plant near London. They learn that Gangrene, however, is on Dr. X’s submarine and headed to another direction.
Action Man decides to go after Gangrene and the rest of the team will handle Dr. X. Unfortunately, this turns out to be a trap. Once Action Man dives into the water, Gangrene uses the MPS to freeze the water. So instead of going after Dr. X, the rest of the team stay behind to save Action Man. Once underwater, and the sheet of solid ice covers the water, Action Man has more flashbacks involving him with a dog, playing on the beach with a mysterious blonde woman ( presumaly his mother), a burning house, him as an adult in school, falling from a plane into a very snowy mountain where he collapses in front of a mysterious door. He also has memories of a monk that says; “The human mind and the human body are the most formidable weapons on the planet,” This is followed with another memory of Action Man atop the Eiffel tower with Ursula. She says, “You should be happy. You’ve done well.” Action Man tells her that he “Has his reasons.” Ursula asks “Will that affect us?” and he simply replies with an “I’m afraid they’re going to.” Action Man kicks back to reality and falls down the water.
Through strange radar technology, Natalie and Knuck search for Action Man. They use a laser gun to cut through the ice and first pull up his speedboat. As they do, Action man has another flashback of the same soccer game. This time, as he stands, another boy, whose face is hidden behind a tree, throws a ball at him, Aiming for his face, but little Action Man catches it.
He kicks back to reality and pounds on the ice to get there attention. It works. Knuck fires the laser gun, cutting a hole and Action Man swims out, breathing heavily.
Soon after, they discover Dr X’s convoy of trucks with plutonium actually IS meeting Gangrene by using the ice he made as a bridge to the sub. At that point, Dr. X sets up a trap by planting bombs on each of the trucks that will go off in ten minutes. This will contaminate the world’s oceans with nuclear radiation. Gangrene decides no one is going to take his “toy”, and tries to make a break for it with the MPS. Dr. X though catches him, and shoots at him. Gangrene falls to the floor, dropping the MPS and Action Man catches it. The skullmen attack Action Man. Action Man takes the MPS and drives off on his speedboat to divert the Skullmen while Knuck and Natalie defuse the bombs, with Dr. X trying to kill them.
Back with Action Man, as the Skullmen chase him, he notices a bunch of seals in his path. He gets some snow from the ice, and throws it at one Skullman, causing a chain reaction where HE smacks into another Skullman, and his snowspeeder crashes into the other. Then, MORE Skullman come after him. Action Man drives up a frozen wave and lands underneath it with the Skullmen on top of it, with no idea where he went. Action Man then fires a missle at the wave, crumbling it and knocking out the Skullmen. Then, he uses some laser on the side of his vehicle to cut the ice around them, and send them sailing to Scotland yard.
But things aren’t going so well for the rest of the Action Force, as Dr. X points out that the ice is melting, with the MPS effects wearing off. The Action Force still has to disarm the bombs. Well, one at least. They disarmed one with another to go. So, while Dr. X and Gangrene make their escape, Action Man returns to save the day, and help Knuck by roping the Truck so that it doesn’t fall into the water. Natalie is seen about to fall off a tipped-over piece of ice. After a bad pickup line from Action Man, he almost falls as well, but the seal he saved before rescues him.
Then, he leaps off the piece of ice and gets hold of the MPS in his snow vehicle, using some awfully impressive gymnastics. He then freezes the water once again, so Natile can get off. With three second remaining, Knuck disarms the last bomb and tells Action Man that he could REALLY use a vacation. Preferably one where “The only ice is in their drinks.”
The next day, after seeing the Big Ben repaired, Knuck comments on breakfast and how he wants nothing cold. Not even the Orange Juice.
- Flashback: This episode had a big amount of flashbacks; Action Man remembers he, as a child, was kept at the bench during a soccer play. He also remembers his childhood dog (from R.A.I.D.), he playing on the beach, his burning house (from You Can't Go Home Again), him as an adult in school (with Ursula sitting next to him in school ), falling from a plane into a very snowy mountain where he collapses in front of a mysterious door.He also has memories of a monk that says; “The human mind and the human body are the most formidable weapons on the planet,” Action Man atop the Eiffel tower with Ursula. She says, “You should be happy. You’ve done well.” Action Man tells her that he “Has his reasons.” She asks “Will that affect us?” and he simply replies with an “I’m afraid they’re going to.” Another flashback of the same soccer game. This time, as he stands, another boy (who is intended to be his brother) whose face is hidden behind a tree throws a ball at him, aiming for his face, but little Action Man catches it.
- After the episode, Action Man gives a message about sunburn and how too much “fun in the sun” can hurt your skin.
