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.
It's the time of year when the wasps build their nests in Ballybeg and everyone is in a flap. The instructions for getting rid of them are in Grandfather Lir's cave but no one can quite remember them correctly. Then Garth and Bev realise the wasps themselves hold the answer! Their nests are made of paper and the children can paint the instructions on it to carry it around. And that's a bit like how T'sai Lun invented paper in far off China.
