Three very different characters live in a world of ideas. Barely noticed, these primordial ideas, which embody everything that defines us as human beings, begin to dissolve. Instead of worrying, the three have fun and celebrate exuberantly while the world around them loses its substance. In the end, they are faced with nothingness. Every ending also holds a new beginning.
