On the kind of stormy night that can change a person's destiny, an enormous sinkhole opens in the middle of Whit Anderson's farm. Braving the rumbling thunder and the driving rain, Casey - their curious Golden Retriever - ventures too close to the gaping maw and tumbles in. Desperate to save her, Whit descends into the darkness, and emerges in a realm beyond his imagining. In this strange world, constantly shifting like the stops and starts of a dream, Whit bears witness to the story of his life and gains the power to change it.
