After a 10-year absence, Amelie, twenty-seven, appears at an old motercycle shop in suburban Paris where she grew up hoping to deal with the animosity between herself and her alcholic older brother Adrien. Amelie fixes an old bike and begins to perform death-defying stunts within a giant sphere of metal latticework. A crew of misfits decides to take the show on the road where disaster and reconciliation await.
