The rock of the Grotto of Lourdes is caressed by tens of millions of people who left there the imprint of their dreams, their expectations, their hopes and their sentences. Lourdes, in southern France, is a catholic pilgrimage center since the apparitions of 1858, with Bernadette Soubirou who declared to have attended eighteen appearances of a woman posing as the Immaculate Conception. Thus, each year, Lourdes welcomes six million pilgrims or visitors from all over the world. In this documentary, there is suffering, direct or indirect. But also faith and hope. A lot of hope! Even after ten or even fifteen journeys in Lourdes. Not to mention the manifold encounters between these people. This documentary is very factual and, in a way, commemorates the 70th miracle, according to the International Medical Committee of Lourdes.
