Christof, Christophe, Christopher and Cristofol are four brothers - sons of the same father and four very different mothers, yet none of them knows of the others' existence. They live in Frankfurt, Paris, London and Barcelona and they share the fact that their father, Gabriel Delacruz - a truck driver - abandoned them when they were little. Years later, when they learn that Gabriel has been declared missing, they come together for the first time and attempt to reconstruct his life and resolve their own doubts about the past. Divided by geography yet united by blood, the Christophers set out on a quest that is at once painful, hilarious and extraordinary. They discover a man who during thirty years of driving was able to escape the darkness of Franco's Spain and to explore a luminous Europe, a journey that, with the birth of his sons, both opened and broke his heart.
