The Block Island Sound2021

Horror Vault's take

Off the rugged shores of Block Island, something unseen has begun to exert a disturbing influence over a local fisherman — blurring the line between mental illness and something far more sinister. His family, already fractured by grief and conflict, must reckon with his increasingly erratic and dangerous behavior. The film leans hard into creeping dread and ambiguity, letting the ocean itself feel like a threat. It's a slow-burn mystery that rewards patient viewers willing to sit with unease and unanswered questions.
