A cowardly king becomes dependent on an evil prince who desires the king's daughter as his wife. As the princess does not want to marry, she is banished to a barren valley as a cattle maid. The king flees and the prince now rules the land with his robber journeymen. On his wanderings, journeyman Hans comes to the lonely valley and defeats the king's daughter's guards. On his further journey, he encounters destruction and devastation. He frees a miller and learns from him that the land can be redeemed from the cruel prince if a fearless person spends one night in the castle.

Beppo Bastelmann and his dog Bolli Spürnase track down Wattfraß. He is hiding in a kitchen where numerous electrical appliances are switched on. When Beppo and Bolli find him here, the electricity devil flees on the streetcar and escapes into the room of a thoughtless employee who has surrounded himself with numerous heaters and lamps. Wattfraß feels at home here and sings his little song of joy. But Beppo and Bolli track him down and don't let him escape again.
