One day while out jogging, Grace witnesses a homicide. She barely shakes off the criminal and escapes with her life. Now, however, she's in a desperate situation because the body has disappeared from the scene and there's no trace left of the crime. The murderer has threatened Grace's life, but the police and everyone else around her doubt her account. The only one who believes Grace is her ex-husband, Ray, whom she broke up with six years ago. Ray is a man who can easily draw in women with his magnetic charm. Although Grace and Ray once chose to go their separate ways, their fates have crossed again.
