Very early in the morning, a flea market in the Parisian suburbs is busy preparing itself for a long day. All before dawn, an eclectic mix of objects are sorted and organized, ready to be bartered. There, an old man assembles a collection of odd objects that he carefully puts in his bag. What is he concocting with this array of recycled junk? The answer might be waiting for us in an anonymous suburban house, where his granddaughter is asleep. His treasure is going to open up the doors to a wonderful world that only she can fully grasp.
