A team of astronauts led by Markary (Barry Sullivan) land on an alien world, and immediately things start to go wrong. Crew members start to act strangely, out of control and attacking their own colleagues.
Some crewmen die and even are bought back to life as murderous zombies on this eerie mysterious world.
Although the sets and costumes are incredibly campy (but to be fair also of the time) and the budget was pretty low, this film is actually rather good at times though let down by the dialogue.
An atmospheric science-fiction horror. It was a big influence on Alien, which did pretty well.
