On a quiet and picturesque coast of California, the calm of a seaside town is interrupted by a strange and thick fog that surrounds the village. The community celebrates Founding Night, but what starts as a festive celebration soon turns into a nightmare. Three teenagers, drawn to the mysterious fog, venture onto a boat, forgetting the warnings of the town's elders. What they don't know is that the fog conceals a dark secret from the past: a century ago, a group of sailors seeking refuge for their ship was betrayed, and now they seek revenge.
As the fog thickens, sinister and spectral figures begin to emerge, targeting the townspeople. Caught between reality and the supernatural, a group of residents, including an unfortunate woman and a radio broadcaster, a mysterious link to the community, will attempt to unravel the origin of the fog before it's too late. Tension mounts as the fog reveals the ghosts seeking justice, ruthless and thirsty for vengeance.
With a haunting atmosphere and a narrative that plays with fear and mystery, the town becomes a battleground between the living and the dead. Will the survivors uncover the truth behind the fog before it claims their souls? The night progresses, and the fate of the town hangs by a thread, like a lurking shadow in the darkness.
