The chief of police orders STACEY, a young and innocent woman-cop, to infiltrate a sweatshop that produces porn films but also organizes orgies for the use of depraved but… rich clients. To do this, she will have to pass herself off as a seasoned actress for whom sex no longer holds any secrets and take the opportunity to accumulate evidence against her employers. At first reluctant, the young girl - who claims to be a virgin and, as such, refuses her fiancé "until marriage" - accepts this very special mission. Stacey then becomes acquainted with a world where "shooting a shot" does not have the same meaning as at the police academy. Very quickly, she learns all about forbidden games and fashionable sexual perversions and plays her role with conviction. But, to her own surprise, she discovers… that she likes it!
