Hard-Boiled Haggerty (1927)

Sinopsis

After bringing down yet another German pilot and escaping uninjured from his burning aircraft, Haggerty (Milton Sills) and his buddy, aircraft machinist Klaxon (Arthur Stone), head for Paris, albeit without an official leave of absence. In escaping from M.P.'s, Haggerty takes refuge in a room occupied by Germaine Benoit (Molly O'Day). Love soon springs up, and Haggerty decides to reform, returning to Major Cotton (Mitchell Lewis) with this resolution. He is unprepared, however, to be awarded a medal for his actions as a fighter pilot. - From Wikipedia
