Season 2 is the second season of the Discovery Channel Television series which focuses on female killers. This season ran for six episode (with three cases per episode) from December 24, 2008 - April 1, 2009.
Each episode has a unifying theme such as jealousy, financial gain, mental illness, or crimes committed by teenagers or the elderly. The titles of the episodes reflect the theme. The stories are told through re-enactments and interviews.
Episodes also feature contributors in relevant fields (e.g. law enforcement, the law, the media, forensic medicine and medicine). Diane Fanning, M. William Phelps, Gregg Olsen, Wensley Clarkson, and Dr. Janis Amatuzio have made multiple appearances. Occasionally, family or friends of the subject or their victims appear to add context and or perspective.
At the end of each segment, the actress playing the subject (and her male and female conspirators, if any) break the fourth wall and look directly at the camera as their fates are revealed. In later seasons, photos of the actual subject are shown.
