The Flying Mail (1926)

Following a party, Sherry Gillespie, a U.S. Mail flyer, awakens to find himself in a strange apartment and is shown evidence by Cleo Roberts that they were married the previous evening. Bart Sheldon, a crook, plots with an associate to pilot Sherry's plane and cautions Cleo not to let the pilot escape. When Sherry escapes and returns to the flying field, he is suspended, then estranged from Alice, his fiancée, by the appearance of Cleo, who is scheming with Sheldon to obtain part of an inheritance that Sherry is to receive if he earns $10,000 in a year. Following a series of fast complications, Sherry tracks down the gang: swinging from a motorcycle to a rope ladder, he mounts a plane, encounters the robber's plane, and fights with the villains. He and Sheldon parachute to the ground, and Sherry is finally vindicated in the eyes of his girl and his employer.
