In this lively spy caper, the male half of a married song-and-dance duo moonlights as a government spy. The trouble begins when he is assigned to monitor a sexy foreign spy, something he must keep from his wife, who soon gets jealous when she sees the two constantly together. To monitor her own husband, the wife gets herself hired as a maid to the seductive secret agent. Her husband, impressed by her natural surveillance skills, finally gives in and allows her to help. Using their special talents, the two investigate and expose a master-spy who has fitted a new kind of carburetor on his airplane. To get at it, the couple dresses up like mechanics and hides upon the plane. Once airborne, they force the pilot out and head back for England.
