Their tender bond reveals a complex relationship - most elephants in Thailand live with humans, despite their wild and potentially dangerous nature.

People increasingly believe that elephants do not belong in the city, in captivity, but should be in the wild, free.

The film explains that illegal tusks are smuggled into the country, making Thailand one of the biggest markets for the global ivory trade.

[3] The film shows how an organization in Thailand is fighting to change the fate of captive elephants: the Elephant Reintroduction Foundation releases them into vast, protected, wild forest habitats within Thailand that are off-limits to humans.

[4] The film was shot in Thailand, over the course of five years, by director Patricia Sims and cinematographer Michael Clark.

The filmmakers were almost killed in a dramatic car accident in 2014, when their vehicle was struck and plunged over a mountainside - fortunately, all survived their injuries.

The film's soundtrack includes songs by Kate Bush/Placebo, Yusuf Islam/Cat Stevens, cellist Jami Sieber, Chris Caddell and the Wreckage, and Geoff Callaghan and The Schopenhauer Incident.
