A daring 450km journey down the Zambezi river brings Tim and Will to the majestic sight of Victoria Falls. But before they can reach Africa’s largest cascade of water, they will face territorial hippos, alligators with a taste for human blood, treacherous jungle rapids, and witch doctors who despise their mission. It is a journey of discovery, both of a remote river and the heart of man, as death is faced everyday and the message of the gospel is preached with every breath.
