On the eve of her becoming an American citizen, Anna Sten is approached by a spy about the weapons-grade pesticide her boss, Harry Davenport, is developing. Later that evening, Davenport is killed and the pesticide is stolen. Suspicion falls on Miss Sten. She is being deported where she escapes with the help of gallant newsman Alan Marshall.
Despite a great cast, including supporting players like Jerome Cowan, Walter Catlett, Jed Prouty, Stanley Fields and Etiene Girardot, and Edwin Justus Mayer co-writing the screenplay, this never rises above the level of a rushed B picture. Few of the players are given a chance to inhabit their characters, so their inclusion in the cast list seems like a waste of time. Neither does the meat of the plot seem to make much sense. Once the formula is in their hands, why hang around to involve Miss Sten further in the effort? Director Otis Garrett had only recently graduated to the director's chair, and would die before he could get out of the Bs. Had this been the typical level of his future efforts, he likely never would have.
