Set on the cusp of the 19th century in Delhi before the British ruled in that region, the drama depicts the fortunes of the residents of Beecham House, an imposing mansion surrounded by acres of exotic woods and pristine lawns. Tom Bateman (Vanity Fair, Jekyll and Hyde) takes the role of enigmatic, soulful John Beecham, a handsome former soldier who has purchased the magnificent mansion, Beecham House, to begin a new life with his family. Wealthy and distinguished, John has witnessed profiteering and exploitation during his time with the controlling East India Company and has resolved to conduct his business as a trader in a more equitable manner. Determined to escape his previous life, John appears haunted by his past, but is inspired to become an honourable member of the region’s trading community. In spite of John’s good intentions his life is shrouded in mystery and when he arrives at the house with an ‘olive-skinned‘ child named August and two Indian nursemaids, Chanchal (Shriya Pilgaonkar) and Maya (Trupti Khamkar), it causes speculation and gossip amongst the servants that he may be the boy’s father. One of the Indian nursemaids, the beautiful Chanchal, is overly protective and particularly fond of the child. Could she be John’s lover and the mother of August? Lesley Nicol (Downton Abbey) is John’s robust, interfering mother Henrietta who has travelled from England to India to stay with her son. She is accompanied by a young family friend Violet, played by Bessie Carter (Les Miserables) who she is determined to help form a union with John. The pair are accompanied by an old friend of John’s, Samuel Parker, played by Marc Warren (Safe, Hustle) who has also left the East India Company and has returned to India for a fresh start. Samuel helps John to find his brother Daniel who he has not seen for 10 years. John convinces Daniel, Leo Suter, (Victoria) to leave the East India Company and join him at Beecham House. Gregory Fitoussi (Mr Selfridge, Spiral) plays General Castillon, a French mercenary working for the Emperor at a time when the French are challenging the East India Company for India. Castillon is suspicious of John and his motives and conspires to stop John being granted a trading licence. Adil Ray (Citizen Khan, Ackley Bridge) is John’s neighbour Murad Beg who dislikes General Castillon intensely and agrees to help John secure a trading licence. Murad’s daughter, Roshanara, (Kanika Kapur) has an English governess Margaret Osborne, played by Dakota Blue Richards (Endeavour) whose beauty and intelligence catches John’s attention. However, when beautiful Chandrika (Pallavi Sharda) arrives at Beecham House with her entourage she is shown to luxurious guest quarters and immediately insists on seeing August. What secrets does Chandrika bring with her to Beecham House?
