Gordon Ramsay on Cocaine, 10.00pm, TV3
This isn't about Ramsay actually consuming Colombian marching powder, it's a two-part series that will see the popular TV chef investigate the drugs industry, which has impacted on his business.
The documentary will see him observe the drug being "cooked" before meeting drug smugglers and the UK police force battling the problem.
Announcing the show, Ramsay explained a personal desire to understand what makes cocaine rife in the restaurant business.
He said: "I've wanted to understand the 'world' of cocaine ever since I lost one of my chefs at my flagship restaurant in Chelsea and I wanted to learn why it's becoming such an epidemic, not just globally but specifically in the culinary world."
