Matt and his friends end up in colonial America during the Revolutionary War by accident rather than by design. The last thing the youngsters could possibly imagine is being magically transported back in time to a whole different world.
And yet that is precisely what happens one chilly night when a three-quarter moon glitters and gleams in the sky as the kids are camping out by Lake Levart. According to local legend, as related by Tony, when there's a three-quarter moon in the sky, an enchanted rowboat magically appears upon the lake from nowhere and takes people off on marvelous adventures.
One of the kids in the group, Katie, goes missing, but she is soon found by the others, who see her standing at the edge of the lake smiling at a mysterious rowboat as it approaches her. It turns out that this is indeed the enchanted rowboat of legend, as mentioned earlier by Tony, and it is ready to take the children on what will be the adventure of a lifetime.
As the others approach the rowboat, all their fears and apprehensions suddenly melt away. They board the rowboat without the slightest hesitation, and before long, they're on their way back into the past, to colonial America during the Revolutionary War.
