Sex And Violence is the 14th episode of Season 4. It aired on February 5th, 2009.
Sam and Dean travel to Bedford, Iowa, where three men have inexplicably beaten their wives to death. The guys realize that behind the murders is a siren, a creature that can take different forms and desperately needs love. It compels people to destroy themselves as a show of devotion. The siren eventually puts Sam and Dean under its spell and pits the two brothers against each other in a fight to the death.
Adam Benson comes home late from work; his wife Vicky is making his dinner and teasing him about being late. Adam responds angrily, but quickly apologizes. Vicky then tells him she has accepted an invitation to a friend's birthday on Saturday. Adam is again angry, and this time he picks up a meat tenderizer and kills her.
In a motel room somewhere Dean wakes, and overhears Sam in the bathroom speaking to someone on the phone, talking about demonic signs. When Sam returns to the bedroom, Dean pretends to be asleep. When he "wakes', Sam says he was talking to Bobby about murders in Bedford, Iowa, where three men have killed their wives.
Posing as attorneys, Sam and Dean visit Adam, who is deeply remorseful and eventually confesses he was deeply in love with a stripper called Jasmine. Adam knows nothing about Jasmine other than that she worked at a club called the Honey Wagon.
Sam visits Dr. Cara Roberts, a doctor who conducted the autopsy on the victims, and took blood samples from the accused. She tells Sam that the men had high levels of oxytocin in their blood, a hormone associated with being in love. When Dean arrives, he is disconcerted at the flirting between Sam and Dr Roberts. But Dean is cheery about having "an actual case involving strippers."
Dean and Sam visit the Honey Wagon, where each of the men had fallen for a different stripper. Information from Bobby indicates that they may be dealing with a siren, a creature originating from Greek mythology, which disguises itself as the perfect mate to lure men.
At the club Lenny Bristol is enamoured with a stripper called Belle. They return to his home, where Lenny cares for his invalid mother. After making love, Belle tells Lenny they can be together forever if he kills his mother, which he does.
The next day, while Dean is alone in the hotel room he dials the last number on Sam's phone - Ruby answers, and he immediately hangs up. Sam returns with news of the murder committed by Lenny Bristol. Bobby calls and informs the boys that the "spell" the men are under is some kind of venom, and that the only way to kill the Siren is with a bronze dagger dipped in blood from one of its victims, so she is poisoned with her own venom. The difficulty is finding someone currently under her spell.
Sam and Dean visit Dr. Cara Roberts with the intention of obtaining a blood sample taken from one of the men while he was still under the Siren's spell. They are met by a Nick Munroe who introduces himself as an FBI Agent and challenges their legitimacy. They tell him to call their supervisor, Mike Kayser, who is actually Bobby, answering a specially labeled phone in his kitchen. Satisfied, Monroe reveals he has also found the link between the men and the strippers. Sam suggests Dean go with him to keep him busy, while Sam gets the blood sample.
As they leave Nick admires the Impala and at the club he and Dean bond over drinks and classic rock. Nick reveals to Dean that he has found a flower, a hyacinth, at the scene of each crime. A flower Dean remembers seeing in Dr Robert's office.
Back at the hospital, Sam and Cara find the blood samples missing, and there are no clues on the security tapes as to the thief. Sam reveals a version of their theory to her, that the men were drugged. He and Cara share a drink and talk about relationships. Cara comes onto Sam, and he responds enthusiastically, even ignoring a call from Dean, and they have sex in her office.
Later Sam calls Dean, who reveals his theory about the hyacinths, and that he has learned that Cara's ex-husband died of a heart attack. Dean accuses Cara of being the Siren but Sam doesn't believe it. Dean guesses that Sam has slept with Cara, and takes him to task over it. He tells Sam he can't trust him, and that he'll handle the investigation on his own. Sam throws the phone away. Dean leaves a message for Bobby and then calls Nick for assistance.
Dean and Nick watch Cara arrive at a club. Dean describes, as Sam did with Cara, a version of the poisoning theory, that maybe it is something in the Siren's saliva, as he and Nick share a hip flask. Nick reveals it is indeed in the saliva, and that he has just poisoned Dean as they shared a drink. Nick is the Siren - and he tells Dean that he can't trust Sam and needs to get him out of the way so he can be the perfect brother that Dean wants.
When Sam returns to the hotel room, Dean grabs him, and holds a knife to his throat, even cutting Sam on Nick's command. Nick describes what a high he gets from having people fall in love and kill for him. Nick then spits venom at Sam infecting him. He tells the brothers that he knows they have issues with each other and that they should fight it out. The survivor will be with him forever.
Dean tells Sam he feels Sam has changed, and knows that he is lying and hiding things from him. Sam reveals the reason is that he wants to hunt Lilith and that Dean is not a strong enough hunter. He taunts Dean about his anguish over his time in Hell. The boys fight violently, smashing through the room door into the hall. Dean gets the better of Sam and is about to swing at him with a fire axe, when Bobby appears and stabs him with a dagger. He then uses the dagger with Dean's infected blood on it to stab the Siren. It dies, and we see its true hideous form revealed. The spell is broken.
The next day Bobby bids farewell to the boys, and they both uneasily apologize for their harsh words, claiming they had no lasting effect.
