Assumptions

Helen and her grandchildren, Jimmy and Beth, take their sad neighbor Peggy Fleming to Nantasket Beach in Massachusetts on the Feast of the Blessed Mother's Assumption into Heaven on August 15th. Peggy wants to assuage her grief for her deceased husband Jim, but the grandchildren are more excited about the ride on the rollercoaster at Paragon Park across from the beach. Will all of their wishes be granted?
