The phrase "booby trapped" gains a whole new meaning in this bizarre blend of sexploitation and espionage, starring the freakishly proportioned Chesty Morgan and written and directed by Doris Wishman. Jane (Chesty Morgan) is a spy working with American intelligence who is ordered to cut short her vacation for a special assignment. An international drug cartel has been smuggling massive amounts of cheap heroin into the United States, and Jane's superiors want the dope men out of commission. Jane is given a list of culprits who are to be tracked down and killed; however, the agency needs evidence that the drug ring has been shut down, so they have devised an unusual plan. A new type of spy camera has been surgically installed in Jane's left breast, which is possible given her remarkable 73-inch bust measurement. After each member of the drug gang has been dispatched, Jane is to take a picture of him using the special camera. However, Jane is working under a rather severe deadline -- if she doesn't finish the job and return to the base within a week, a bomb planted inside the camera will explode, killing Jane and those around her. Double Agent 73 was the second and final collaboration between Chesty Morgan and Doris Wishman; Morgan would shoot a small role in Il Casanova di Fellini before dropping out of movies, while Wishman would remain active in filmmaking up until her death in 2002.
