Somewhere in the Bavarian province the robber Hotzenplotz is up to mischief. One day he robs Kasperl's grandmother's coffee grinder. Since the goofy sergeant Dimpfelmoser sees little hope of finding the robber, Kasperl and his best friend Seppel decide to track down the robber themselves. With a ruse, they manage to find the robber's cave, but are then caught by Hotzenplotz, who sells Kasperl to the magician Zwackelmann.
