Young Tom Long is forced to stay with his kindly Aunt and Uncle while his brother recovers from a bout of the measles. At their flat, he is disappointed to find there is no garden to play in; but his disappointment turns to wonder when he discovers a magical garden which only appears at night when an old grandfather clock strikes thirteen. His nightly excursions to this beautiful garden become even more interesting when he realises that the people he meets cannot see him - except one young girl named Hattie.
