Filmmaker Marco Carlucci follows the incredible journey of pianist/composer Alessandra Celletti who organizes traveling free concerts on a truck-stage. This is 'piano piano on the road', a crazy idea that became possible thanks to the support of fans and many small communities that embraced the project. An unusual tour in which the emotions of a musician and her piano on four wheels travel thousands of miles, playing in places rich in beauty and in hidden corners of Italy.
