S5·E16 Black and Blue

While working at Sunrise House--a shelter for battered women--Holly receives a distress call from Sharon Grayson who says her husband is going to kill her. When Mike and Holly arrive at the scene, they find the husband dead--with two bullets in his body--and Sharon is nowhere to be seen. While Holly believes that Sharon was truly in danger, no one seems to agree, including Allie Grayson, the deceased's daughter, Michael and Donovan. Holly changes her mind, however, when some evidence turns up that shows that Sharon may not really be who she says she is.
