Jack is up for anything... as long as he doesn't have to get wet. No one knows about his fear of water, and he's determined to keep it a secret. But then he slips into a shallow stream and is pulled out of a deep, fast-flowing river gorge by Bear Grylls. They work together to build a bamboo raft, navigate the whitewater rapids and steer clear of hidden dangers... Can Jack rise to the challenge of being thrown in at the deep end? Will he sink or swim?
