Doris Day shows a surprising affinity for satire in this Cold War spoof, starring as a publicist in a space laboratory who's falling in love with engineer boss Rod Taylor while writing a biography of him. Various governments are interested in Taylor's work and, as Day has a dog called Vladimir, she quickly becomes a Soviet suspect. Director Frank Tashlin was a former cartoonist and packs the film with sight gags, but Day rises above the slapstick.

Bruce, the owner of an aerospace company, is infatuated with Jennifer and hires her to be his biographer so that he can be near her and win her affections. Is she actually a Russian spy trying to obtain aerospace secrets?
