The miniature killer reveals he/she is still at large by sending Grissom an especially chilling miniature that forewarns a woman and her cat are scheduled to die the next day.

With potentially less than a day to attempt to prevent the next murders, the CSI team must quickly shake off their shock that the true miniature killer is not the late Ernie Edward Dell, who committed suicide after confessing to the slayings. Grissom ponders why the killer deviated from his/her eerie tradition of leaving the miniature at the crime scene after the murder. He also laments that he held up the investigation by being on sabbatical when the unmarked package with the miniature arrived for him.
