Two septuagenarians pack up their lives and leave their life-long home in Pennsylvania for retirement in sunny Florida. After a wrong turn and a fall into some bubbling waters, an unwitting sip from the Fountain of Youth magically makes them 25 and toned...with grown grandchildren, elderly neighbors and decades of shared history to reconcile. With interference from a love-struck sprite, the two unlikely heroes take a comic journey full of fresh temptations, unexpected opportunities and hard choices.
