When the CIA learns that a pair of hypnotists, code-named The Thirsty Pigeons, have been hired to kidnap and brainwash Shelby, the CIA's most attractive female agent, they suspect it to be the work of Dr. Polygamy, an evil billionaire with an insatiable desire for more wives. However, during their attempted kidnapping, The Thirsty Pigeons are inadvertently captured by Shelby, who discover that they have a striking resemblance to a couple of CIA agents she know, her ex-boyfriend, Robbie Miller, and the falsely accused culprit for the break-up, Elson Marsh. Now in an attempt to rescue all the kidnapped wives from Dr. Polygamy's island, Robbie and Elson must learn to reconcile their own mysterious past and go undercover as The Thirsty Pigeons, bringing with them Dr. P's targeted fiancee, Shelby.
