Allie Hutchins, a Boston lawyer, has had a bad experience on a hijacked bus. She's still having nightmares and panic attacks. It seems like a good idea to go home to Tyler, Missouri for a while. Because nothing every happens in Tyler, and that's what Allie needs--several weeks of peace and quiet and sanity. Except Missouri is being besieged by monsoon rains. Everything's under water. And there's a significant part of the population who thinks the rain is a sign from above, that God is reacting to the proposed Indian gambling casino. When Allie runs into an old acquaintance, Michael Quinn, things get more complicated, and, finally, deadly. But why is Allie the intended victim?
