Fathom (1967)

Synopsis
Raquel Welch breaks the surly bonds of Earth and loves every minute of it in this lighthearted spy spoof. Fathom Harvill (Welch) is an American skydiver touring Europe with a U.S. parachute team when she's approached by Douglas Campbell (Ronald Fraser), a Scottish agent working with American intelligence. According to Campbell, a triggering mechanism for nuclear weapons has gone missing in the Mediterranean, and Douglas wants Fathom to help find it. After encountering Chinese operative Peter Merriweather (Anthony Franciosa), Fathom discovers that Campbell is actually a private eye and that she's been tricked into helping him snag some jewelry. But what's the whole truth, and whose side is Fathom supposed to be on? ~ All Movie Guide
