Danger Mouse is back, fighting fit and ready to pit his wits against the mad Baron Silas Greenback in the Black Forest Gateau. Whoops! Chateau. Colonel K, head of a top secret department in which he does not know its names, sends Danger Mouse, along with his trusted assistant Penfold, to the Black Forest to destroy the Pi-beam, the Baron's secret weapon which poses a threat to world security. After DM says that it is an easy task, he and Penfold leave for Germany in their mousemobile. Unfortunately, finding the Pi-Beam would be difficult since the Baron has set many traps that DM needs to overcome.
