Croc Swarm

During the wet season, saltwater crocodiles lay their eggs in freshwater, where the locals dig them up to control the population of these formidable predators. Matt and his team are on a mission to collect 20,000 eggs from their nests before it is too late. Flying above the nests in a chopper, Matt is lowered by his own invention, which separates the man in the nest from the protective mother croc.
