Synopsis: In school, they were best friends. And they shared two passions: the plane they built together, christened Bela Cielo, and a girl. Sayuri.
Oblivious to the tense international environment, the three form an indelible bond and it seems nothing can ever come between them and their dream. The boys believe that someday they will reach the distant tower - and touch Sayuri's heart - however far away it may be.
But time passes. War escalates. Alliances are changed. Friends become enemies. And Sayuri falls into a dreamlike state that seems inexplicably linked to the mysterious tower of their youth. At the brink of a World War, Sayuri seems to be the key to a new world peace...or a frightening and bitter end to life as we know it.
