An Island Out of Time is a half-hour documentary about Smith Island that features Mary Ada and Dwight Marshall. Their lives personify the Chesapeake Bay’s seafood-harvesting culture and history, but their four children chose to break with that tradition. The film, like Tom Horton's 1996 book, An Island Out of Time, is both a celebration and elegy for a place beset with erosion, dwindling population and vanishing economic opportunities.
