Then the next night, one of the saucers lands by the reservoir. The creatures that come out of the ship don't look like people at all. Their heads are too large and their eyes are too big and black. Worse, the want Adam and his friends to come with them for a little ride in space. In fact, the aliens insist that they come. Then the flying saucer takes off! And it doesn't look like they'll be coming back anytime soon. Can Adam, Watch, Sally, and Andy figure out a way to get home?
