This highly charged, emotional film captures rare and never before seen images of the southern population of Humpback Whales. Australian wildlife specialist, Tina Dalton, takes us on an adventure onboard the 100-year-old tall ship the 'Anna Kristina'. She embarks on a journey together with a team of scientists and underwater specialists to observe and interact with the curious whales of Platypus Bay, off Australia's coast. You'll witness the enormous rescue efforts by locals to free a young humpback whale stranded helplessly on a nearby beach. In another spectacular display, males battle for supremacy with nearly disastrous consequences for human onlookers. Tina goes underwater with these gentle giants and watches an inquisitive whale approach her from out of the depths. In a beautiful finale, the whale extends his enormous pectoral fin to touch her so gently, like an underwater handshake, that it can only be seen as an act of trust.
