The Lone Wolf Spy Hunt is a 1939 American adventure film directed by Peter Godfrey and written by Jonathan Latimer.

The film stars Warren William and Ida Lupino and was released by Columbia Pictures, on January 27, 1939.

[4] Michale Lanyard, the "Lone Wolf," is kidnapped off a Washington, D.C. street and taken to a man whose face is hidden in darkness.

The plans for the new Palmer anti-aircraft gun are stolen from the War Department and a cigarette deliberately left to incriminate Lanyard.

Police Inspector Thomas knows Lanyard, one of the few capable of doing the job, is long retired and it is an obvious frameup, but is eager to seize any opportunity to try to jail him anyway.

A widower, he tells his young daughter Patricia that he is sending her away to school, while his pretty heiress girlfriend Val Carson is fuming because he left her at lunch to take a phone call and did not come back.

He triggers the burglar alarm, then watches undetected as Gregory, his vengeful nemesis, opens his concealed safe to check if his share of the plans is still there.
