An incredible mystery plays out beneath the waves. Marine biologist Nan Hauser is an expert in the behaviour of whales. One day, in the breathtaking surroundings of the Cook Islands, Nan is shooting footage for a nature documentary when a 45-tonne humpback comes charging towards her. In seconds, she’ll find herself picked up and swept along by the enormous creature, balanced on the tip of its vast jaw. What on earth is happening? And how can Nan hope to emerge in one piece?
