Animation about a time-travelling brother and sister called Garth and Bev, who live in harmony with nature in their village long ago. They are transported to different times and places by the Time Spiral and solve problems with the help of Grandfather Lir. Poor little Enda the Eagle, he's learning to fly but keeps crashing into things because he doesn't know how to turn yet. Garth and Bev discover just which feathers he needs to move to turn in flight. As a treat, Lir sends them to meet Wilbur and Orville Wright whose great discovery used the same principles as inspiration for their aeroplane.
