Captain Scarlet and a team of Spectrum operatives go to Mars to check the reasons for the lack of contact with Elysium base. On approach they are shot down by a missile, apparently fired from the base. At the base they find all the staff dead from a strange series of injuries. Scarlet quickly realizes they are not alone on the planet. He needs to identify what killed the crewmen and neutralize the threat before his own team becomes victims
