One summer evening in the year 1848, three Cardinals and a missionary Bishop from America were dining together in the gardens of a villa in the Sabine hills, overlooking Rome.

Eusabio and the Tesuque boys went quietly away to tell their people; and the next morning the old Archbishop lay before the high altar in the church he had built.

One summer evening in the year of 1848 three Cardinals and a missionary, dining in a villa near Rome, decide the fate of a simple parish priest, the Frenchman Jean Marie Latour. He is to go to New Mexico to win for Catholicism the South-West of America, a country where the Faith has slumbered for centuries. There, together with his old friend Father Vaillant, Latour makes his home. To the carnelian hills and ochre-yellow deserts of this almost pagan land he brings the refined traditions of French culture and Christian belief. Slowly, gently he reforms and revivifies, after forty years of love and service achieving a final reconciliation between his faith and the sensual peasant people of New Mexico: a harmony embodied in the realisation of his most cherished dream - a Romanesque cathedral, carved from the Mexican rock, gold as sunlight.
