The Baron and Penfold are stranded together on a desert island. In the skies above King Kong Brunel's desert island, the Mark IV and the Frog's Head Flyer are in a race to snatch Brunel's All Encompassing Remote Control - an incredible device that can 'switch off' anything it is aimed at. Greenback's henchman Stiletto struggles to fly their Flyer while fending off Danger Mouse with a laser cannon.
Stiletto is overjoyed when his laser beam hits the Mark IV, but not before somehow splitting the whole island in half, causing the huge dormant volcano to rumble back to life. Both vehicles crash land and Penfold finds that he is stranded in the company of Baron Greenback and Nero on one side of the island, whilst Danger Mouse is marooned with Stiletto and Rocket Sloth on the other.
As Danger Mouse struggles with Stiletto and Rocket Sloth, Penfold and the Baron surprisingly form a happy bond, settling into an idyllic friendship, which sees the Baron swear that he will never use any type of nasty doomsday device ever again.
The volcano suddenly erupts and Penfold finds himself in a fix, cornered by the flow of hot molten lava! Will Baron Greenback help to save his new friend with the All Encompassing Remote Control, and will Danger Mouse actually be able to get Stiletto and Rocket Sloth to work together and help with the rescue?
