One by one, the guilty fall. They don’t just die – they transform. Their veins turn red. They walk into the sea singing. Diego’s own father is taken on a moonless night, leaving behind only a wet footprint on the dock.
The town is now trapped. The lighthouse suddenly activates on its own, but its beam is red.
DR. VALERIA SOTO (30s, sharp, haunted by a past failure in her field) arrives on Isla Santa Marea after being summoned by her estranged aunt, a local elder. The town’s fishing industry has collapsed.
