On a Caribbean island dominated by a technological regime, Kai, a resistance engineer, flees after being discovered and is rescued by Bernardo, a diver with a voice capable of moving even the waves. Their connection is born in danger, but fate separates them before they can fully know each other. Years later, Kai is reunited with Bernardo, but he no longer recognizes the man who risked everything to save him... because his voice, his only memory, is lost forever.
