Nans and Mouts begin their new adventure on a small island off the coast of Cannes in the Mediterranean Sea with a dream as crazy as it is unexpected: to cross France and organize a hot air balloon concert flying over the legendary Mont-Saint-Michel. As always, they set off without money, clothes, or a technical team, relying solely on the generosity and solidarity of the people they meet along the way to advance their journey. To realize their dream, they must travel more than 1,000 kilometers across France, find accommodation and food, and meet a hot air balloon pilot, someone eccentric enough to raise his voice in the sky above Mont-Saint-Michel. All this without a single penny.

As usual, Nans and Mouts set off naked and penniless from Lozère with a dream: to organize a small dance show on the water. They head for the magnificent Salagou Lake in the heart of Hérault. On foot, by bike, by canoe, or even hitchhiking, Nans and Mouts travel these sublime lands and rivers in search of dancers, musicians, and even sound equipment. This could take the form of a floating ballet, a ball on a flotilla of boats, or many other finds. Everything is always orchestrated by the greatest of chance and, above all, punctuated by wonderful encounters. Thanks to exchange, gifting, and bartering, Nans and Mouts must once again use perseverance and confidence to move toward their dream, as poetic as it is crazy.
