Henriëtte has promised to do some cooking for the store-lady. Two dimwitted crooks decide they want to burgle the Poppenkraam. One of them poses as a spy to trick the storekeeper.
When Henriëtte is baking cookies a man comes round to look for his unmanageable daughter Thea, aka 'Krengetje'. The girl soon turns out to be hiding in the kitchen and is more clumsy than ill meaning.
