Jenny Neumann takes a group of men into the jungles of Kenya to look for her husband, and instead finds a tribe of caveman-looking "Near-Men" who all seem terribly attracted to her beautiful blond hair.

After returning to Los Angeles from a group therapy session, documentary filmmaker Bob Sanders and his wife, Carol, find themselves becoming vigilante couples counselors, offering unsolicited advice to their best friends, Ted and Alice Henderson. Not wanting to be rude, the Hendersons play along, but some latent sexual tension among the four soon comes bubbling to the surface, and long-buried desires don't stay buried for long.
