Big wave pioneer Ross Clarke-Jones and two-time world champion Tom Carroll are two Aussie surfing legends who have spent the last few years scouring the ends of the earth to ride the most dangerous waves they can find. Now they’re taking the search to New Zealand and the freezing temperatures, rugged terrain and inhospitable conditions of remote Fiordland.

But hunting waves the size of a four-storey building involves strategy, timing and preparation, not to mention tracking precise enough to lead them to largest oceanic storms in the world. That’s where meteorologist and surf forecaster Ben Matson comes in. Using the latest storm prediction technology, he helps Ross and Tom track swells and time their arrival to the hour in a mad, high-stakes race against time and the elements.

Their adventure into the unknown terrain of Fiordland sees them overcome almost impossible challenges, deal with the harshest conditions of their careers, have Mother Nature test their tracking skills to the limits and come face to face with an Antarctic storm.
