Bones belonging to Chrissy Foster, a mother missing since 1972. Her fifty year-old son Wally Foster's memory of the night she disappeared, unlocked during a Deep Brain Stimulation treatment for his Parkinson's Disease. Moze Foster, the uncle who raised Wally and his sister Lisbeth with enough love and responsibility for two parents. And Moze's brother Luke, a Vietnam War hero who chooses five tours as a CAP Marine rather than the responsibilities of husband to Chrissy and father to Wally and Lisbeth. Throw into the mix an overzealous Assistant DA who sees Moze as her headline machine to advance her career and you have Unlocked a little mystery, a little history, and a whole lot of focus on the Foster family's journey that starts in 1967 with two brothers split by the Vietnam War and ends in a field near a small village in Vietnam fifty years later.
