Ashley and Josh, a popular YouTube couple known for chasing dangerous adventures, decide to film the ultimate forbidden journey: a trip to North Sentinel Island. Ignoring international warnings and laws meant to protect both outsiders and the island’s isolated inhabitants, they set foot on the island and are never heard from again.
When news of their disappearance reaches the authorities, a covert rescue mission is launched. Brian and Rachel, highly trained members of the military, are assigned to locate the missing couple and extract them if possible.
From the moment their helicopter approaches the island, however, something feels deeply wrong.
