In 2019, Léon Passuello, a 35-year-old father and sailor, dreams of creating the first regular sail-powered maritime route between Quiberon and Belle-Île-en-Mer. Alongside his three friends—Lou, Inès, and Jonas—all passionate sailors in their thirties, Léon embarks on a daring journey to make this dream a reality. Against all odds and in the midst of a global health crisis, they push forward with their ambitious project, which few believed in at the start. The Road is Blue is a heartening and unconventional road movie, celebrating hope, imagination, and the pursuit of freedom, no matter the challenges.
