An expectant couple arrive on a scenic island off the coast of Mexico, only to wage a desperate fight for survival against a vicious gang of murderous children in this remake of the 1976 horror classic Who Can Kill a Child? Francis (Ebon Moss-Bachrach) and Beth (Vinessa Shaw) are vacationing in Mexico when they rent a boat to visit a nearby island known for having its very own Carnival. But by the time they arrive on the island, the festival has ended, and the streets are empty. Curiously, the only people they can find are young children who seem to roam the area without supervision. Attempting to check into a local hotel, Francis and Beth hear what appears to be a desperate distress call on the radio, but can't make out the language. Later, Francis watches in horror as the local children attack and disembowel an elderly man in the streets. Horrified, he runs back to the hotel and encounters a shell-shocked father who reveals that the children on the island have all gone insane, killing every adult in sight. As the laughter of children echoes through the streets, Francis and Beth realize that they must run and never look back if they ever hope to make it out of this nightmare alive.
