The first three films in the series deal with the implications of an emotionally neglected, sexually assertive young woman's fascination with her best friend's father, and how her desire for him affects multiple individuals who fall under her influence.
The fourth film in the series is only thematically linked to the first three, dealing with a secret society of young women dedicated to obtaining control over powerful men through seduction.
Although the first film in the series received critical acclaim at the Sundance Festival and developed a cult status through word of mouth marketing, the next two films were released direct to video and received a generally negative reception, with the fourth premiering as a made-for-television movie.
