If nothing ever scares you, then be warned, be scared of the Venetou. Unfortunately the people of New Caledonia, one of the colonies of Earth, encountered them when one of their survey ships bring them back to the colony. The alien vampire that can disappear from sight by hypnotising anyone near to it. When their people begin to die they first need to discover what is killing and feeding upon their people. Secondly they need to find a way to see the vampire, and finally they need a man who was capable of taking the fight to the Venetou.
