On October 28th 1890 the great wall of the Barsdon Dam gave way, and the Eagle Star reservoir buried the small Arizona town of Jackson Hope under forty feet of water. Men, women and children perished in the devastating flood, nobody survived. For over a hundred years the town lay forgotten at the bottom of a vast lake, but it has been a particularly harsh summer in Arizona, and the town is starting to emerge. Experts will come and survey the land, hoping to prospect for a bright and lucrative new project, but they will get more than they bargained for. Bit by bit they will uncover the truth behind the disaster which wiped a small farming community off the map, and as they do they will learn with devastating consequencies that some secrets should stay buried forever.
