Scottish chef Tony Singh travels to India - the country of his ancestors - to trace his family roots and discover whether his mum's Punjabi cooking is the real deal. He begins his journey in Amritsar - draped in lights for the festival of Diwali - before braving the treacherous Grand Trunk Road to Delhi, a place Tony has only ever visited twice. Along the way, he fulfills a boyhood dream to meet the Nihang, nomadic Sikh warriors whose cooking techniques are legendary. He receives an exclusive invite to eat and cook with a Maharaja and, as his waistline tightens thanks to the rich Punjabi diet, he burns off the calories at Bollysweat, the fitness phenomenon taking Delhi by storm. As Tony gets under the skin of Punjabi ways, he discovers how the Sikh religion and the region's troubled past have created a food and culture like no other. He ends his epic adventure at the ancestral home in Delhi, where his 93-year-old uncle Ameer opens a window on his family history he will never forget.
