Thailand, June 23, 2018. A soccer coach and 12 players, aged 11 to 16, visit Tham Luang cave. Surprised by the sudden monsoon rain, the group finds themselves trapped in the flooded cave. When Thai Navy SEALS are unable to rescue them, English divers are dispatched who are experienced in exploring underground rivers and who, thanks to their expertise and their composure, manage to navigate the submerged corridors.
Ten days pass before the boys and their trainer are finally found, on a ledge located four kilometers from the entrance to the cave. The rescue operation has only just begun.
