On the trail of a dangerous energy field, the members of Torchwood are led to Delhi. There they witness the simultaneous disappearance of hundreds of people, and Jack discovers that the field centres on an old colonial mansion — Torchwood India. Jack is shocked to find that Torchwood India is still going strong — he shut it down himself over 80 years ago. He's even more surprised to find that its members, including his old flame the Duchess, haven't aged a day. What is the secret of their eternal youth, and how is it linked to the deadly energy field? The team must find out — and they haven't a moment to lose, for all the time the field is expanding...
The mansion holds amontillado among its wine stores.
An energy field is being used to permanently suspend time at Torchwood India and the nearby settlement to keep its occupants from ever aging. This practice began when the Golden Age of the country began to decline and the members of this Torchwood branch decided to keep time at a standstill so that they could enjoy eternal youth and fortune.
When the energy field is broken, everything it contained disappears when the time differential caused by keeping Torchwood India frozen in time corrects itself in the present day.
The Duchess states "the 20th century was when it all changed," a take on Jack's opening narration, "the 21st century is where it all changes," only considering the past instead of the present and future. Similarly, Alex Hopkins told Jack the 21st century is the moment everything changes. (TV: Fragments)
Winston Churchill is mentioned as partly to blame for the fall of India's golden age by the Duchess, which leads her to target him as a threat to eliminate when she pushes the world back through time. Churchill would later appear and prove his dubious nature in TV: Victory of the Daleks.
