In the sun-scorched, seemingly idyllic coastal town where Charlie Higgins’s character seeks a fresh start, the past has a dangerous way of washing ashore in this tense psychological thriller. Written and directed by Oscar Brett Archibald, "Sandcastle" follows a young man who, haunted by a traumatic event, retreats to a remote beach house to escape his demons. His fragile peace is shattered when he crosses paths with a mysterious local woman, played by Delta Anderson, whose own secrets run as deep as the tide. As a series of unsettling occurrences begin to erode the boundaries between reality and paranoia, the protagonist finds himself trapped in a web of buried truths and fractured memories. With a cast including Holly Burton, Bailey Parks, and Ben Pritchard, the film builds an atmosphere of creeping dread, exploring how the very structures we build to protect ourselves can become prisons. "Sandcastle" is a slow-burn mystery about the fragility of the mind and the devastating weight of what we choose to forget.
