Hotel Poseidon

Hotel Poseidon streams in the US on ARROW, as of October 6, 2026.

A day in the life of reluctant hotel owner Dave, a man troubled by nightmares, his neighbour, his friends and love. Dave’s days and nights blend into each other as he wanders vacantly through the halls of the abandoned and dilapidated Hotel Poseidon, which he inherited from his deceased father. When a young woman knocks on the hotel’s door looking for a room, while Dave’s best friend wants to throw a party in the backroom, and a recurring dream haunts him, a surreal and grisly ordeal is set in motion.
