At the start of this novel the narrator confesses to his father that, twenty years earlier in the last years of Franco, he was asked to give a lift to some ETA activists. Thus begins a process of reconstruction of the things that have never been said between father and son, the reasons for their disagreements, hidden in their silences. The son has a double motive to take on this memory exercise: his father has just been diagosed by the doctors with a degenerateve mental illness and has also received a letter demanding payment of a rebel tax.
The father has already begun to inhabit that strange territory where time and space are gradually overcome by the forces of forgetulness. And as for the world of violence, he soon finds that wanting to get away from it is not enough.
