Two men are isolated on a remote island lighthouse. As days blur together, sanity erodes. Power struggles emerge, reality fractures, and mythology bleeds into daily life. The lighthouse itself becomes an object of obsession, representing forbidden knowledge. The film never confirms what is real. Instead, it traps the viewer inside unreliable perception. Guilt, repression, and masculine dominance drive the descent into madness. The ending implies punishment for seeking enlightenment without restraint. This is not a story about insanity arriving suddenly, but about isolation amplifying what already exists inside the mind.
