Sipowicz and Clark investigate the murder of an irrational female Corrections Officer who tempted fate. What at first seems like a clean murder becomes murky when Clark learns her own disturbed mental state may have played a part in her own murder. After realizing she was murdered for her weapon, despite her mild lunacy, Clark makes the right decision and puts the shooter away. Meanwhile, McDowell is assigned a new partner, none other than Eddie Gibson, a detective who has a reputation for being incompetent. The two investigate the murder of another woman who may have been a victim of spousal or maternal abuse, with a surprising twist. When they learn she was both an alcoholic and suffered from multiple sclerosis, the killer turns out to be from her own family.
