Sounds of Obsession (2008)

Overview

Krista (Sunrise Adams), is the frustrated wife of a radio producer who leaves her every morning to work side-by-side with an ex-porn star and sex-talk radio host. Her husband is distant and unaffectionate at home, and is extremely focused on work. Meanwhile, Krista's friends are cheating left and right, and Krista is having fantasies about banging someone else for revenge. It's not surprising that she becomes fixated on the idea that her husband is having an affair. When Krista finally breaks down and gets off with a studio engineer right on the floor of her husband's inner sanctum, the guilt drives Krista towards drastic measures that will ensure her husband's co-host never gets in the way of her home life ever again.
