Based on the true story of 44 year-old Clara Harris, a successful Texas dentist and mother of 4-year old twins who hired private investigator Bobbi Bacha (played by Sela Ward) to spy on her orthodontist philandering husband, David Harris. Instead, Bacha ends up videotaping his client running over her husband three times with her Mercedes-Benz in the posh parking lot of an upscale hotel and killing him. During the trial, Clara's in-laws came to her defense while her stepdaughter testified against her. In the end, a Houston jury convicts Harris for first-degree murder.
