In a remote, sleepy coastal town, longtime friends Jake and Tom stumble upon a mysterious old journal while exploring an abandoned house on the cliff edge. This journal, filled with cryptic writings and warnings about strange phenomena, piques their curiosity. Over time, they notice peculiar events happening around the town: animals acting strangely, electronic devices malfunctioning, and unsettling weather patterns. The boys become obsessed, diving deeper into the journal's secrets. As they follow its instructions, they start seeing ghostly figures near the cliffs at night. These figures are silent yet seem to beckon them, urging them to discover more about the journal's origins.

When they confide in their friend Sam, the trio becomes determined to unravel the truth. Sam, initially skeptical, is drawn in after experiencing strange dreams connected to the eerie phenomena. Together, they piece together the journal's history, uncovering a link to a secret society that once thrived in their town decades ago. Their investigation leads them to hidden passages within the cliffs, suggesting secrets buried deep beneath the town itself. Tensions rise when the friends realize that powerful forces want to keep these secrets buried at any cost. As their discovery threatens to alter the town's peaceful existence, the group must decide whether to unveil the truth or protect themselves from unseen dangers lurking before dawn.
