The Lady Has Plans (1942)

PAULETTE'S BACK...is the objective of the front! Fun...and how! Thrills...you bet! Romance...well, you'd better ask Paulette!

Some dastardly criminals have stolen some top secret plans and tattoo them on the back of a woman so she can sell them to the highest bidder in Lisbon. This woman plans to take the place of a 'Sidney Royce', a legitimate traveler going to Lisbon as a reporter. Crossed signals allows the real Sidney to reach Portugal first, where she is pursued by those trying to obtain the plans and US government agents trying to prevent the sale.
