Mexico, December 9, 1531. Ten years after the Spaniards conquered this land, on a hill on the outskirts of the capital, something inconceivable happens to Juan Diego, a native of the area. At dawn a heavenly figure comes to meet him, revealing herself as "Mary, mother of all men." To confirm the first vision, the Lady not only entrusts him with several messages. But, also, in the final vision, leaves her portrait mysteriously present on his tilma. It is the portrait of a young woman looking downward. She is clothed in a dress figured with roses and a mantle spangled with stars.
