In 1966, during the Vietnam War, Joan Hunter, an ordinary housewife, mother of four from the small, idyllic coastal town of Scituate, MA, spearheads Operation Morale Booster, a mission to ensure that every deployed American G.I. receives mail at weekly mail call. Armed only with her typewriter and her vibrant personality, she reaches thousands of soldiers and especially captivates one battle-tested soul, Bob Johnson. She is white, he is black; she is married, he is not. This potentially scandalous relationship transcends society's rules of engagement due to their honest and thought-provoking candor.
