Told through the harrowing experiences of the Van Rossem family of Kuyfoort, this is the story of the great flood that swept over Holland in January, 1953. The courage and heroism of the people in their fight against the encroaching sea, the search for and rescue of survivors and the reclamation of their homes and land are depicted. "How the wind blows tonight! As if it wants to tear the house up by the roots," says Tante Anna. But the van Rossem family isn't worried. Isn't their house strong and solid? And the dikes that hold back the sea—aren't they strong, too? That very night they waken to the shriek of sirens and the clang of church bells. They hear an even more frightening sound, too—the rush of water flooding the house. And then comes the cry that strikes terror to the heart of every Dutch boy and girl: "Get to your attic. The dike gave way!"
