The Metal Men are set to perform at the Settlement House, for neighborhood children. En route, Platinum notices a lonely little boy, sitting on the stoop in front of his home. Platinum attempts to entice the boy into attending the show at the Settlement House, but he rudely rebuffs her. The Metal Men each take their turn performing feats for the children, starting with Mercury. Platinum, however, is distracted by the lonely little boy's refusal to attend. After Iron and Lead surprise their creator, Doctor Will Magnus, with a new trick, it's Platinum's turn to take the stage. Platinum, however, refuses.

Leaving the Settlement House, Platinum returns to the lonely little boy. The boy, Timmy, is blind, a condition he hid from Platinum early. It is also due to his blindness that Timmy did not realize that one of the Metal Men was actually inviting him personally to their show. The rest of the team has followed Platinum back to Timmy, and warmly introduce themselves to the boy. With Timmy's mother's permission, the team offers Timmy the chance to spend an entire day with the Metal Men. Platinum tells Timmy that Magnus can cure his blindness, placing the inventor in an awkward position.

Though Magnus knows it's hopeless, he goes through the motions of looking for a cure. Magnus locks himself within his laboratory, dreading the moment he must tell Timmy that he has failed. Meanwhile, the Metal Men take Timmy up into orbit, on board their rocket ship. Suddenly, caught in a powerful cosmic turbulence, the rocket is drawn away from Earth, into deep space. The Metal Men are tossed, haplessly, about the cabin. To save Timmy from injury, Platinum spreads herself out into a wire mesh between Timmy and the Metal Men. The rocket ship arrives at a distant planet, seemingly devoid of life.

Strangely, the sole feature is a deserted amusement park. After checking the atmospheric conditions, the Metal Men take Timmy to the amusement park. Platinum notices that Timmy counts the steps and turns as they make their way to the park. Timmy explains that this is how blind people navigate. Lead notices that none of the rides seem to have motors, or control mechanisms. The group climbs into the cars of a roller coaster, that then activates itself. As soon as the roller coaster begins it's plummet down the track, metal tentacles with pincers emerge from the cars.

Gold, Mercury, and Platinum, carrying Timmy, quickly exit the cars. Iron holds the tentacles at bay, giving Lead and Tin the chance to escape. Tin, though, refuses to let Iron sacrifice himself for him. Tin tries to hold the tentacles back so Iron can escape, but the humblest Metal Man begins to buckle. Grabbing Tin, Iron leaps them both to safety. Suddenly, another ride roars to life, and rains it's missile-shaped cars down on the Metal Men. Molding themselves into rockets, Iron and Lead smash their way through the theme ride's projectiles. The Ferris Wheel then launches itself at them.

Mercury winds himself into a cork screw, then pierces the Ferris Wheel. With Iron anchoring Mercury, Lead spins the wheel, which revolves around Mercury's body, high into the sky. Reaching the end of Mercury, the Ferris Wheel crashes to the ground. The group flees en masse from the rest of the now animated amusement park rides. On the edge of the park, the Metal Men are flashed by an enormous camera. The bright light overloads their optic sensors, rendering the Metal Men blind. The Metal Men rely on Timmy to lead them back to their rocket ship. The rumble of the amusement park rides fills the air with thunder. Following Timmy, the now sightless Metal Men race back to their rocket as fast as they can. The theme park rides, though, are rapidly closing in.
