Women wait anxiously at a minehead in Capodarso, Sicily. Their men are underground. The mine is closing and the miners refuse to come up unless the owner relents. After three days, they give up in despair... In a bar in town, Ciccio is recruiting workers for jobs in France. He can get people over the border - for L20,000 a head. Enough people to fill a bus sell their belongings to pay the fee, including Saro and his 3 young children, and Barbara and her man Vanni, in trouble with the law and desperate to flee Italy. After reaching Naples by train, Ciccio tries to slip away but is grabbed by Vanni. Vanni tells Barbara where to meet at the border if anything should go wrong. In Rome, Ciccio points out Vanni to the police. In the shoot-out, both Vanni and Ciccio escape. The others are arrested. They are ordered by the police to return to Sicily or be charged with "illegal expatriation". With Saro as leader, and nearly out of money, they head north instead. Hardship draws Saro and Barbara closer together...
