The storyline is quickly told: the robber Hotzenplotz has his eyes set on Granny's beautiful coffee grinder that plays a tune when coffee is ground. For some reason I forgot he ends up taking both Granny and coffee grinder and now enter Granny's grandson Kaspar and his slightly goofy friend Seppl who are called upon to free both Granny and her coffee grinder and bring the robber Hotzenplotz to justice.
