Astrid the fly relaxes by the window, daydreaming about the outside world. Meanwhile little sister Zazza has disappeared! We follow Astrid through the kitchen, where she discovers the mysterious yellow holes, watering goody bag, and over the terrifying black fluff (a block of cheese, the compost bin, and the family cat). Will Astrid find Zazza? Or maybe she’ll discover the place she’s been dreaming of?
