The world is in jeopardy and the only thing that can save it is a 1,000ft Penfold.

Danger Mouse and Penfold must stop a deranged Victorian time-travelling chimp from uninventing the world.

It's Crimicon - the Annual Criminal world convention - and DM and Penfold are joined by a brand new secret agent to stop Isambard Kingkong Brunel from selling a potentially catastrophic custard bomb doomsday weapon.

A geeky ancestor travels back in time to stop Danger Mouse from destroying the world.
