Craig and Jackie Adams-Maher of the Australian Reptile Park head out in search of one of Australia's deadliest snakes - the death adder - whose venom is desperately needed to help end a shortage of antivenom, now down to a dangerously low supply. Their trip takes them across New South Wales to Lightning Ridge, where they make a dramatic capture of two Eastern Browns - an aggressive snake that kills more people than any other in Australia. After Craig takes a break by attempting to ride a bull at a local rodeo - (and learns that bull wrangling and snake wrangling don't have much in common) - they bag another stunning snake - an eight-foot King Brown. But Death Adders continue to elude them. Finally, in the hills outside Sandy Hollow, their luck changes. Jackie makes her first free-hand capture of a Death Adder, and Craig uncovers a second. And on their way home, they strike gold - a litter of 15 baby Death Adders. But even that is only a start - since it takes hundreds of milkings to obtain one vial of antivenom, Craig and Jackie's Death Adder Duet will go on.
