In the pre-World War II innocence of small-town America, a dapper off-Islander impresses the locals. Drawn to the prettiest girl, he is upset when an elderly woman tries to break off their romance. In a drunken stupor he murders the troublesome woman. Through an amazing confluence of circumstances, he avoids prosecution.

The reclusive, paranoid teacher of the victim attracts the attention of a distracted district attorney who is eager for a sensational trial to promote himself in an impending election. The teacher is arrested and charged with the murder. The looming shadows of war on the international stage capture the people of Martha's Vineyard, and the local murder fades into the murky memoirs of history.
