The Baltimore detectives are working overtime on the Redball investigation of "Samaritan of the Year" Catharine Goodrich's murder. New Shift Commander Megan Russert heads the Redball investigation and Giardello is called in to oversee the investigation. Meanwhile, Beau's wife kicks him out, leaving Felton to break into his own house to pick up some clothes. Exhausted by dead-end leads, Russert goes home. Felton shows up, ostensibly to give her information on a suspect, but in fact they are having an affair.
