In 1993, 25-year-old Martin Garnett is already earning good money at a car dealership in Sydney, but he's hungry for more. When he agrees to body pack thirteen bags of Class A drugs from Thailand to Sydney for $200,000 in cash, his lifestyle is about to change dramatically…. but not in the way he hoped. At Bangkok airport, a security guard gives him a friendly pat on the back and he's immediately pulled over, stripped naked and discovered to be carrying 4.7 kilos of heroin - enough to receive the death penalty. Miraculously, Martin's sentence is reduced to 40 years because his court hearing falls on a Buddhist holiday. Now, he must learn to survive Thailand's most dangerous prisons to become Australia's longest serving prisoner overseas.
