Double Agent 73 is a 1974 American exploitation spy film directed and produced by Doris Wishman and starring burlesque performer Chesty Morgan.
Chesty Morgan, a woman whose bust is 73 inches (1.9 m) in size, plays Jane Tennay, a large breasted secret agent.
Even though the light is on and disregarding the huge difference in breasts' size, the sleepy guy thinks she is his girlfriend.
It turns out the agency planted a time-bomb inside the camera, as an insurance policy in case she is captured.
Double Agent 73 is an ostensible sequel to Deadly Weapons, also directed by Doris Wishman.
