How can tomorrow ever be as good as today? Afraid of tomorrow, a little boy puts all his scientific knowledge to use in an attempt to turn back time and stay in the wonderful past. Luckily, his grandfather discovers him exploring the wormholes in the garden, trying to find a way back - and by showing him the photos of some of his wonderful past experiences, reassures the boy that there is plenty to look forward to and that every day gives the chance for a new adventure.
