Indecent Behavior 2 (1994)

Synopsis
A sex therapist is forced to turn detective to keep herself out of prison in this steamy thriller. Journalist Shoshona Reed (Elizabeth Sandifer) has a knack for digging up incriminating information -- enough so that she's begun blackmailing a number of people and threatening to run incriminating stories about them if they don't pay up. Shoshona is a client of sex therapist Rebecca Mathis (Shannon Tweed), and when Shoshona is killed, Rebecca becomes a suspect in the murder investigation. To save her own skin, Rebecca begins investigating Shoshona's death, and she discovers that there are a number of people who might have wanted her dead, including Darrell Martine (Chad McQueen), a disturbed ex-convict, and Tom Mueller (Craig Stepp), a businessman with a secret. Indecent Behavior III followed this picture a year later. ~ Mark Deming, All Movie Guide
