Meet Hula, one tough young shark with a very special extra sense. In the shallows of Hawaii, life is hard. Catching enough food and avoiding bigger sharks isn't easy to do on your own. Only one in ten baby hammerheads survive to see their first birthday. If she does reach the age of one, Hula will then have to leave Hawaii, otherwise she will starve. This means an epic journey to find waters teeming with life, thousands of kilometres away. With all these challenges, will our star of the show make it?
