Hanna's return home from the hospital should be a joyous event, but being stuck in a wheelchair and feeling haunted by "A" makes her return feel more like a Hitchcock nightmare than a proper homecoming.
The BAU team travels to San Francisco to investigate the murders of several homeless men and teams up with a separate group of BAU operatives who are working another case they think is connected.
