Garth and Bev - Television

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. Morc and Skelly have gone fishing but without checking the weather forecast with Lir first. There is a storm coming and Garth and Bev have to send them a message to warn them. When they figure out that making a big pebble picture of a storm cloud on the beach really gets the message across they get to go and see John Logie Baird and the first TV broadcast!
