When alien vessels from the Hydra constellation crash‑land on Sardinia, they capture a leading scientist, his daughter, several technicians and two Eastern spies, forcing them to repair the ship’s damaged engine. After the repairs, the aliens lift off, taking the humans aboard. A mutiny ensues, sending the craft hurtling into the endless void.
