The Girl Next Door is an intimate and humanizing look into the rise to fame of adult film superstar Stacy Valentine. The wheels were set in motion when Stacy's then-husband, to satisfy his own sexual fantasy, urged his Oklahoma housewife, Stacy Baker, to submit her photograph to Gallery Magazine's amateur pictorial competition, voyeuristically named "The Girl Next Door." Easily winning this contest, Stacy was soon gracing the cover of Hustler magazine and accepting offers to perform in X-rated films. Stacy allows the audience to experience the exotic world of pornography through the eyes of a former housewife from Oklahoma.
