The BAU travel to Akron, Ohio, where two sets of married couples have been murdered in the span of a week. The husbands, who had Viagra in their system but who were not prescribed the drug, were shot while the wives were stabbed. The couples were forced to have sex with the husband wearing a condom, before they were killed. In reviewing the crime scenes, Morgan and Prentiss determine that the unsub is not a sexual sadist as he was trying to set a romantic mood for the kills, and is compensating for a probable recent bout of impotence. In interviewing the victims' families, the team also determine that the husband is the key to the unsub's targets as stereotypical alpha male types. When the unsub hits a broader target, the team are only then able to figure out how the unsub is able to gain access to the victims without a struggle, and from where he has devolved. Meanwhile, Hotch is surprised by an applicant for the communications liaison job. Despite the applicant not being an obvious choice, Hotch gives the applicant a trial on this case with some surprising and not so surprising results.
