In October 2021, Christina Parcell was found stabbed to death in her South Carolina home. When authorities arrived, they found a gruesome scene: Christina's body in a pool of blood with 36 stab wounds and mysterious rose petals strewn throughout the home. Police begin looking for a killer and set their sights on those closest to Christina, including her fiancé and her young daughter's father, with whom she had a contentious custody battle, though both were later found not to be the killer. But when a Ring doorbell camera captures an image of a man riding a bicycle and then entering Christina's home around the time of her murder, it leads them to a courtroom confession that no one saw coming.
