At six, Dario watched the first Moon landing on TV, sparking a lifelong dream to reach the stars. For the rest of his life, the ingenious curmudgeon built a homemade space rocket on his farm using scraps from the local hardware store. But, after a disastrous first launch burns down the neighbors' cornfields, Dario lands in jail. Enter Mario, his estranged brother who left the dying countryside for the big city: despite the confusion, he agrees to help Italy's 'secret space program' finally take off.
