When Donato fails to rescue a life at sea for the first time, he eventually meets Konrad, a German speed bike rider, a friend of the drowning man. Donato travels with Konrad to Berlin and disappears, leaving his younger brother behind. Years later, Ayrton, as a teenager, ventures in search of Donato for a reckoning with the one he considered his hero.
