A couple share a house, but one with quite a difference. They both walk upright, but she uses the floor as the floor; he uses the ceiling as the floor. The share certain facilities - like a fridge that slides up and down the wall to accommodate both of them, and their house glides through the sky in a style straight from "The Wizard of Oz". Then, in a similar vein, it crash-lands on the ground and after some tumbling adopts an upright position. All of a sudden, she has the ground permanently and he must improvise, upside down, and avoid nosebleeds. I must admit that I was actually quite puzzled when I saw her solution, but once I understood it it's really quite ingeniously fun and actually quite a potent critique on the nature of marriage and of how it is not always perfectly aligned. I love this kind of stop-motion animation, especially when it is peppered with some gently comedic scenes that add a new dimension to domestic bliss (or lack of it!) and it's really well worth a watch.
