Skipper Dwane leads his crew into the waters of Fiordland. It's all hands on deck as the divers work relentlessly to collect tonnes of urchin. As the weather deteriorates, one of the crew gets a scare from below the surface.
Dwane's friend and fellow diver, Tim, joins the team as they collect a slimy alternative to urchin. Along for the ride is 16-year-old Storm, who is determined to make his mark as a valued member of the crew.
The crew heads to the southernmost part of Stewart Island, the last stop before Antarctica. Despite the icy waters and cold conditions, the competition between the divers is fierce - although for one member of the team it will be their last trip.
Skipper Dwayne and the crew head to a consistent urchin dive spot. A keen young dingy boy, George, endures a baptism of fire as the team tries to fill a backlog of orders.
