Mr. Blair's Labyrinth

Two teenage brothers are looking for some summer fun as the camp out at Grampa's historic lake home.  When they arrive, Grampa is turning an old garden into a labyrinth.  The boys help, and as they do, learn the history of the house.  That night, under a full moon, they decide to walk the labyrinth.  It's midnight on Midsummer's Eve, a most magical time, when one of the boys is granted a wish.  The year is no longer 2012, but 1935, the bleakest part of the Great Depression.  Now trespassers on someone else's property, the boys flee.  Their adventure takes them to many places, but they are always searching for a way back home.
