When the sprinkler in a garden of a house sprays blood, the police and the CSI arrive at the scene. Soon they find the four members of the Chambliss family are murdered in the house that is covered in blood. They find a trail of blood to the neighbor John Lee that is arrested and soon he confesses the murder spree. They learn that John Lee is a pedophile that has changed the clothes with blood of the eight-year-old Fiona, for whom he was obsessed. Then a woman, Leslie Gitig, comes to the police station and tells that they had arrested the wrong killer since she had murdered the family. The CSI investigation shows that a man called Lonny Gallows might have killed the family, but his father Maurice says that he had killed the family and not his son. The reasonable doubt is formed and Russel mentions the movie "Strangers on a Train".
