Two spaceships, the Argos and the Galliot are investigating a new planet and decide to land and explore. When the Galliot lands it looses contact with the Argos, which then crashes to the planets surface. When the crew wake they start attacking each other, before coming to their senses. They then find the Galliot, with its crew dead, but before they can bury them all, some of the corpses go missing. They slowly realise that they are not alone and there is the possibility that a race of bodiless aliens are taking over their bodies!
AIP co-produced this film giving them some control over decisions and installed an international cast of actors including American Barry Sullivan and Brazilian Norma Bengell, as the two leads. Bava in turn provided AIP with a wonderfully realised sci-fi, featuring beautiful fog shrouded landscapes, and crews in futuristic leather space suits, belying the low budget nature of the film.
