Greenwich, Connecticut, 1922. Newspaper man Joe Henry finds himself the primary suspect when his friend, fellow reporter Wynton Gresham, is murdered. Both were veterans of French battles during WWIthe war that was supposed to end all wars. Unanswered questions pile up in the wake of a violent night Gresham lies dead in his home, a manuscript he had just completed has gone missing, three Frenchmen lay dead in a car accident less than a mile from Greshams home, and a trunk full of Greshams clothes lay neatly packed in his bedroom. Hours after his friends death, Henry discovers in Greshams desk drawer a one-way ticket reserved in his friends name aboard a steamer ship to France. The ticket is dated for the next day. Henry steals away under Greshams identity, escaping the heated interrogation of the town sheriff, to Paris in the roaring 20s.
