Several tenants occupy a house on the Prague outskirts. In the worst apartment lives the Valenta family: the devout Mrs. Valentová with her crippled son Martin and daughter-in-law Pepča, who reproaches them for her having to feed them. One day the parish organizes a pilgrimage to Holy Mountain and Father Jan offers the poor Valentas a free journey. The mother visits the cathedral, in her prayers she supplicates God for the mitigation of their sufferring and presently she dies exhausted. But her words have been heard. The son, broken-hearted by his mother's death, is bothered by fire and smoke in the house. The neighbour woman Marešová has carelessly cast aside a lit match and the house has burst into flame. The scared Martin subconsciously gets up and then faints. But the neighbours rescue him. He meets the residents of the house in hospital and they are witnesses to a great event: Martin is once again able to walk and he reconciles with Pepča. Father Jan congratulates Martin, reminding everyone that genuine faith is the curative of man.
