The Worm is planning a heist that will help him to become the most powerful and brilliant criminal in the world. He uses his burrowing machine piloted by Grub to burrow into prison and free the criminals, Roto Chopper and Bugsy Busby. They free the criminals and The Worm tells them his plans and what they must do.
Blue Falcon and Dynomutt are on patrol trying to figure out what The Worm is up to. They check all the places that have helicopters since the reason that The Worm would want Roto Chopper is to steal and fly a helicopter. They check the navy base last. Dynomutt is distracted and The Worm and his cronies steal a couple of helicopters and Blue Falcon and Dynomutt take off in pursuit. They catch up to the helicopter and board it only to be sealed inside as The Worm and the others go to the second helicopter. Blue Falcon and Dynomutt escape the helicopter after it makes a spashdown out in the ocean and they head back for shore using Dynomutt's boat motor.
Meanwhile, The Worm and his men steal the super computer from Big City Tech. Blue Falcon and Dynomutt show up too late to stop them. Blue Falcon has a plan and they go to the city power plant where they broadcast a bulletin about Professor Zilch (Dynomutt in disguise) pulling the power by taking out the master fuse. He does and the power goes out. The Worm is determined to get the fuse back so he can use his computer. He sends Roto Chopper and Bugsy Busby to get it.
They catch Dynomutt in the grocery store and Dynomutt uses the Falcon Beeper to lead Blue Falcon to The Worm. Blue Falcon gets there but he is caught. While The Worm is distracted, he frees himself and Dynomutt. They chase after The Worm ins his digging machine with the Falcon Car and its digging attachment. They force the Worm to dig up into prison and he is caught and put in jail.
the computer is returned to Big City Tech where Dynomutt tests its ability and is showered with applesauce.
