A young hotel concierge falls to her death from a balcony and is impaled on a statue shortly after an ugly incident with a popular model participating in a rooftop photo shoot. While Mac and Stella investigate the case, they hear gunshots coming from a nearby building and discover the shots came from a penthouse loft. When they enter, they find a woman standing over two dead bodies, one of them her husband. The woman claims the other victim was beating her husband, so she shot the man.
