The Block Island Sound 4K Ultra HD delivers a chilling blend of ecological and cosmic horror in the world-premiere UHD release of the McManus Brothers’ acclaimed modern genre film. Directed by Kevin McManus and Matthew McManus, this eerie slow-burn horror explores paranoia, environmental collapse, and inherited trauma along the isolated shores of Block Island.
 
Something is wrong off the coast. Birds fall from the sky, fish wash ashore, and an unseen force begins to affect the town’s residents in deeply unsettling ways. As Harry Lynch watches his father slip into violent confusion, his sister Audry returns home with her daughter, uncovering a connection between the island’s strange phenomena and her work in marine biology. What begins as quiet unease escalates into a terrifying reckoning that threatens both family and community. Starring Chris Sheffield and Michaela McManus, The Block Island Sound unfolds as a tightly constructed psychological horror that rewards patience with mounting dread.
 
Presented here in stunning HDR10 with immersive 5.1 surround sound, this 4K Ultra HD edition marks the definitive home video release of a film praised for its atmosphere, intelligence, and emotional weight, accompanied by a strong slate of behind-the-scenes features and director commentary.
