The work of a Thailand hospital devoted solely to treating elephants.

A night-time emergency stretches the hospital as three sick female elephants from the same sanctuary are admitted with colic. One of the patients arrives with her four-month-old baby, who stays while her mother receives treatment, but it proves to be a massive task to nurse these big patients back to health.

Filmed over four months, this series follows the work of a Thailand hospital devoted solely to treating and saving the lives of elephants. In the first episode, the team of vets are giving an elephant an endoscopy to check on the progress of her cancer treatment, and Paul O'Donoghue helps an elephant arriving with chronic diarrhoea.
