The animated anthology consists of three novellas, the action of which unfolds in different eras. We are waiting for the stories of three of the most savage killers in human history: a Viking woman who tells her son the story of a mysterious monster that kills all living things; a ninja in feudal Japan who is ready to kill his own samurai brother in a struggle for inheritance rights; a pilot during World War II trying to figure out a strange invisible force in the sky threatening allies. These three can take down anyone on Earth, but for the alien hunter, they are just another prey.
