In an attempt to overcome her shark phobia, Tanya Streeter travels to a shark hot-spot in the Indian Ocean, to meet the massive sharks of the Maldives. Her goal: to dive with the biggest shark in the world. But she is soon terrified out of the water by 2-foot long reef sharks. It takes an encounter with a spectacular shoal of manta rays to tempt her back in. In this difficult personal journey, Tanya freedives at night amongst feeding white-tips, discovers the curious deep-living zebra shark and comes face to face with the largest fish in the sea: the mighty whale shark.
