A teenage boy, Marlon, is being prosecuted for a murder of Stacey, one of his female classmates. During his trial, his 12-year-old sister Hannah takes the stand, and admits that she herself murdered Stacey. The CSI team is now faced with a strange dilemma - two confessions for the one murder. As Hannah is a genius, in high school already, some CSI members suspect that she could not have physically committed the murder. Finally the brother is found to be not guilty by the jury. Later, Hannah reveals to Sara that it was Marlon all along.
