Danger Mouse, the world's greatest mouse detective, and Penfold, the world's greatest mole sidekick, return with six further adventures. In 'One Hundred and Fifty Million Years Lost' Danger Mouse takes a trip through time and has a close shave with a pterodactyl. 'The Planet of the Cats' sees Penfold captured by the diabolically fiendish Baron Greenback and Danger Mouse trying his best to save him. 'Four Heads are Better Than Two' finds the rodent superhero acting very strangely indeed. 'The Tower of Terror' has the heroic duo climb the Rock of Gibraltar and encounter a giant gorilla. 'The Great Bone Idol' places mouse and mole face-to-face with the evil Count Duckula. And finally, at last, in 'Public Enemy Number One' it seems that Baron Greenback's secret headquarters might have finally been exposed.
