The documentary reveals the unique artistic collaboration between visual artist JR, former Daft Punk member Thomas Bangalter, and choreographer Damien Jalet. By combining their respective talents, they created "Chiroptera": 154 dancers from around the world perched on the scaffolding of the Palais Garnier in Paris. Together, they offer us an extraordinary performance. In the fall of 2023, the Paris Opera asked artist JR to transform the construction site on the façade of the Palais Garnier into a creative playground. By inviting Damien Jalet and Thomas Bangalter to create a performance for 154 dancers with him, he embarks on a human and artistic adventure with complex technical challenges. This documentary takes us behind the scenes of this show. How will the challenge be met?
