Elephants carrying Trunkcam, Tuskcam and other spy cameras tell the story of four cubs growing up in the Indian jungle.

From the day their eyes open and they tumble out of the den, Tiger - Spy in the Jungle captures the lives of four tiger cubs as they grow up alongside their devoted mother. The elephants continue to film the young stars as they grow into adult hunters. Over two years, the elephants help capture the most intimate portrayal of tigers ever filmed. They also reveal the secret life of the other extraordinary creatures of the Indian jungle.

In the first programme, the elephants come upon the four 10-day-old tiger cubs. This is their mother's first litter and she has her paws full as they tumble from the den, only to be carried back to safety in her massive jaws.

As they grow they move from her milk onto meat. Fortunately the tigress is a skilled hunter. Charger, their imposing father, keeps his distance but helps to protect his vulnerable offspring from rogue male tigers and leopards. As they grow, they face encounters with sloth bears, pythons and pangolins. Their mother keeps them safe, until one day the cubs are left home alone and their arch rival, an Indian leopard, is about.
