Paul (Rufus Sewell) and Jeanne (Emmanuelle Béart) lost their young son, Joshua, in the 2004 tsunami, and cling to the hope that one day they'll find him. Believing she sees Josh in a brief video of orphaned children, Jeanne convinces Paul to undertake a rescue mission. The couple spends the last of their savings on a journey into the jungles of the Thai-Burmese border, where unknown threats await them. Fabrice Du Welz directs this dark odyssey.
