After their divorce, Visiting Nurse Melanie Bass must keep in contact with Dr. Artie Krapaneck, her philandering ex-husband, as they share custody of her beloved dog, Bruno. When she arrives at a Connecticut highway rest stop to retrieve the dog for "her week" she discovers the body of her ex-husband along with that of an unknown woman. It seems that now Artie will finally be out of her life forever. He isn't. He left a "legacy" that now puts Melanie's own life in danger - as well as Bruno's.
