Single mom Emily Locke is building a new life with her daughter. Hoping to spend more time at home, she's relocated to Houston and put her career on hold to work part - time for her private investigator friend, Richard Cole. It's a nice balance between work and family until Emily finds out she's been working for the attorney who defended her husband's killer.<br/>The discovery nearly destroys her friendship with Richard, but Emily resists abandoning socialite client Claire Gaston, who awaits trial for the murder of a local plastic surgeon. The threat of losing her children to a self - serving ex - husband terrifies Claire more than the specter of a life behind bars. <br/>Claire has been leading a wildly unconventional life and passing around access to her home and assets like popcorn. Should she be condemned for bad choices? Emily, haunted by her own, doesn't think so. <br/>Meanwhile, Emily's wild - child friend Jeannie, in town for a visit, sees a chance for Emily to loosen up when a mysterious note leads her into a daring undercover ruse at a high - brow ladies' health club. Emily fakes conformity with Houston's elite debutantes and trophy wives in a surreal fitness subculture where things, and people, are seldom what they seem. At this gym, ''killer workout'' takes on a whole new meaning.
