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.

The vets check the heart health, dental health and gut health of their majestic patients, and a young bull elephant is rescued after breaking his leg in a violent thunderstorm. Later, laser technology is used to help save an elephant who has been brought into A&E with severe burns.
