I tre aquilotti

At the Royal Air Force Academy of Caserta, three students, Mario, Marco and Filippo become great friends. Toward the end of the course, Marco accidentally meets and falls in love with Mario's sister, Adriana. Mario expresses his opposition to Marco and this causes the end of their friendship. Due to an accident during a training flight, Marco is passed from the role of the navigator to the services role, thus not obtaining the military pilot's license.
