[3] Vega Aircraft Corporation employees pilot Bill Morley, a former Flying Tiger, is awaiting commissioning with the United States Army Air Forces.

As all donors are given the temporary use of hospital white coats, wolf bachelor Bill sees his chance to get Penny's address and details by impersonating a doctor.

Penny decides to get her revenge by attempting to humiliate Bill by turning him over to one of the Craig family's raving hypochondriac friends and introducing him to a real medical professional.

Penny instantly falls in love with Bill and tracks him down by getting a job herself at the Vega Aircraft Factory as a riveter that also satisfies her desire to help the war effort.

Hers to Hold was originally planned to be filmed in 1942 and titled Three Smart Girls Join Up to be directed by Jean Renoir and produced by Bruce Manning with a screenplay by Paul Gallico and Richard J. Collins.

[16] The Boeing B-17 Flying Fortress shown being built in the film flew several combat missions with the Eighth Air Force over Europe, where it was named Tinkertoy.

The review also indicated: "Story, although lightly contrived, generates audience attention through the deft business generously inserted in the script and carried through via direction".
