The marriage vow "till death do us part" lives up to its promise for the couples featured in "Happily Never After." It's a wedding show and police drama rolled into one, as the best days in the lives of brides and grooms tragically turn when homicides crash the honeymoons. Each episode tells the true story -- narrated by actress Marlo Thomas -- of a newlywed's murder, interspersed with flashbacks to happier days for the couple. Dr. Wendy Walsh, who holds a Ph.D. in clinical psychology and is a co-host on the syndicated program "The Doctors," offers commentary on the behavioral twists and turns in each story.
