Aliens attack! The aliens arrive with their mothership and hide behind the moon. They are shapeshifters and disguise themselves as iguanas when their team land on Earth. Their targets are schools and children because they believe they can shapeshift into human children and find out more about humans and their lives. Find out what happens to the team members, and whether they can complete their mission. When one of the alien shapeshifters loses her tail, she has no choice but to join forces with a human child, one of the aliens bonded with him and lets him know that she was an alien shapeshifter. Thus, the destinies of the boy and the alien become inextricably linked.
