The conclusion of Gordon Ramsay's investigation into the criminal business behind the global cocaine trade. In the UK, he meets a major dealer brandishing two packets of cocaine worth £70,000 and a recovering addict who has spent an estimated £0.5million on her habit. In Columbia he joins an elite anti-drugs squad on a high-risk helicopter mission in Columbia, and in Honduras he is witness to the aftermath of a murder - before meeting armed assassins who boast of having killed in cocaine-related 'hits'.
