The Impossibles are attending a science fair and one of the main attractions is a gold brick. As everyone is looking at it, the evil Dr. Futuro appears from the future and steals the brick and returns to his time, 2,000 years in the future. The Impossibles borrow an experimental time machine built by one of the scientists at the fair. They are transported to the future and face off against Dr. Futuro. One by one, Dr. Futuro stops The Impossibles. After he traps Coil Man and Fluid Man, he goes to check on Multi Man and finds out that he is waiting for him. Multi Man chases Dr. Futuro and gets hit with an aging ray. The others get free and help return Multi Man to his correct age by using one of Dr. Futuro's machines. They chase Dr. Futuro and he runs into the machine and it turns him into a baby. The Impossibles use another of his machines to return themselves and the gold back to the present.
