While staying with his aged relative, miles away from his home and friends, James finds a playground, complete with a stream and a waterfall running through it. On the other side of the water, is another young lad, much the same age. Someone who is as keen to have a friend as he is. James crosses the bridge and enters Gordon's world. They uncover an ancient sword. They can't tell anyone about it or they will be in trouble so they hide the object until the following year. Only, things don't go to plan. James returns but things have changed. His friend is nowhere to be found. Instead, James finds himself drawn into adventures and mysteries crossing time and space. James finds himself caught up in events from the 1960s, 1066 and even the Gunpowder Plot. He and the sword must now work together to try to keep history on track.
