After a wild round of sex on the bottom floor of Spike's crypt, Buffy and Spike carry on a real conversation about decorating and Buffy's feelings for Spike. Spike asks Buffy if she even likes him, to which she replies, "Sometimes." Pulling out a pair of handcuffs, Spike then asks Buffy if she trusts him to which she replies, "Never." Meanwhile, The Trio, now hiding in a rented house after being forced to flee their lair, have put the finishing touches on a new gadget, the Cerebral Dampener. The evil tool will allow the three to turn any woman of their choice into their pseudo-willing sex slave.
Buffy takes a break at her job to talk in private with Tara. While secretly rubbing at her handcuff burned wrists, Buffy admits that Spike is able to hurt her, but not other humans. Suspicious that she returned to life "wrong" because of the resurrection spell, Buffy asks Tara to do some research to see if she can find out just what is "wrong" with her.
Warren Mears browses a bar for attractive women while Andrew Wells and Jonathan Levinson are able to watch through a camera in Warren's tie and direct him to various women they would like to have as slaves. Irritated by the suggestions, Warren removes the earpiece and microphone and approaches someone familiar: his ex-girlfriend, Katrina. Katrina wants nothing to do with Warren, but he uses the Cerebral Dampener and suddenly, Katrina refers to her ex as "Master".
Buffy returns home after a long, hard, dirty day at work to find her friends preparing for Xander and Anya's wedding by teaching Dawn to waltz. Buffy becomes upset when she learns that Dawn is spending the night at her friend Janice's house, but she decides it is better for her to go to the Bronze with her friends than to stay at home at brood.
The Trio enjoy champagne served by Katrina, who has been dressed in a maid's outfit, and admire Warren's selection of women. Warren takes Katrina away for his private use and while kissing, Warren asks Katrina to say things to him. When it becomes clear that sex is what Warren wants, Katrina manages to shake of the effects of the Cerebral Dampener. She then lets loose on Warren and his buddies and reveals to Jonathan and Andrew that she is Warren's ex-girlfriend; they think that is messed up. Katrina goes on to tell The Trio that what they were planning to do to her constitutes rape, a revelation that shocks Jonathan and Andrew. Katrina then tries to leave the confines of the basement, but Warren hits Katrina with a champagne bottle and she falls to the stairs, dead. Warren formulates a plan to get rid of the body, but Andrew and Jonathan are not eager to cover up the accidental murder.
At the Bronze, Buffy and Willow talk about Willow's recovery while watching Xander and Anya dance jubilantly together. Willow joins the couple on the dance floor, but Buffy does not, choosing instead to visit the bar only to change her mind and head upstairs to the balcony. For a moment, she is alone, but she is soon joined by Spike. Hidden away, Spike and Buffy have sex while he speaks on the subject of the reaction of her friends if they found out the truth about the two of them. Buffy closes her eyes at the thought, but Spike tells her to open them, to watch her friends while she gets away with it right under their noses. He invites her to remain in the shadows with him.
While Willow and Xander are making their way to The Magic Box, they encounter Tara who's on her way out of the shop with a book. Willow and Tara talk about the magic book Tara holds and Willow's success with staying away from magic. They part ways.
That night, Buffy is supposed to be on patrol, but she finds herself in front of Spike's crypt instead. He senses her arrival, but when he opens the door, she's already bolted.
As she resumes her patrolling duties, Buffy hears a woman screaming and follows the sound. She then finds herself in a twisted scenario where her surroundings shift between the attack of several demons, the crying woman and Spike finding Buffy in the woods. In the end, Buffy strikes out at something and instead of hitting one of the demons, she hits the woman whom the viewer recognizes as Katrina. Katrina's body rolls down the hill as Buffy rushes behind trying to catch her. When Buffy finally does catch up, she realizes that Katrina is dead and assumes that the blow she dealt killed her. Watching from afar, an apparently still living Katrina watches.
Spike escorts Buffy away from the scene and back to her house.
Inside their van, Warren is pleased with the success of their efforts as the Katrina double returns to the van and shifts appearance to reveal a very bitter Jonathan.
That same night, Buffy dreams of Spike joining her and comforting her in her bed. Her dream shifts and they're in his crypt with her on top and Spike bound by the handcuffs. With Buffy still on top, Spike becomes Katrina and the crypt becomes the woods. Her dream shifts again and we see Buffy lowering a stake to Spike's chest. When Spike becomes Katrina again, Buffy asks her, "Do you trust me?" Katrina's eyes open wide as the stake is shoved into her chest.
Shaken by her dream, Buffy wakes and dresses and then goes to Dawn's room. She professes her love to her sister and then admits that she was involved in an incident earlier that night and that she has to go to the police about it. Dawn is scared and becomes upset by the idea of losing her sister.
Spike catches Buffy outside the police station and tries to stand in the way of her turning herself in to the police. He says that he took care of the body, but then two cops passing by reveal that the body was found washed up by the river. Despite the fact that Spike's attempt at a cover up is unsuccessful, he's still determined to stop her from admitting guilt. He feels that the fact that she's saved thousands, she shouldn't have to pay for accidentally taking the life of one. As Spike vamps out and attempts to physically restrain her from going to the police, Buffy takes out her frustration and anger on Spike, and he does not retaliate, saying that she should "put it all on him". She punches Spike repeatedly in the face, declaring that he is evil and soulless, and that there is "nothing clean in (him)". After beating him senseless, Buffy is shocked by what she had just done, and walks dazedly away from Spike
She enters the police station and learns that the girl in the woods was Katrina Silber, whom she recognizes as Warren's ex-girlfriend. Buffy leaves without discussing the incident with the police.
The Scooby Gang research and find that the demons Buffy encountered in the woods caused the time shifting and from this they conclude that Katrina was probably dead before Buffy even encountered her. Buffy knows Warren is connected to the incident and wants The Trio found and dealt with.
The Sunnydale Police rule Katrina's death to be due to accidental drowning (a particularly incompetent "solution" since Katrina, already dead for a half-hour or more before Spike dumped her in the river, cannot possibly have had any water in her lungs; Spike clearly did not expect her to be found at all, so it seems unlikely that he put water in her lungs to simulate drowning), and Warren and Andrew are pleased with the general success of their murderous actions. Their only disappointment is that Buffy didn't actually take the fall for Warren's crime. However, Jonathan is not the slightest bit pleased at all.
After researching the resurrection spell, Tara is able to inform Buffy that the spell didn't bring Buffy back "wrong". Tara explains that the only effect the process of re-materializing had on Buffy's body and soul was something akin to a molecular suntan. This effect didn't make Buffy more or less human, she's as human as she ever was, but it was just enough of a change to confuse Spike's chip. Buffy then confesses to Tara that more than just an exchange of punches has been going on between her and Spike. Tara is supportive, first asking Buffy if she loves Spike because if she does, it's okay, since Spike did a lot of good the previous summer, and Tara, unlike the other Scoobies, believes he truly loves Buffy. Buffy does not reply. Then Tara tells Buffy that if it isn't love that Buffy feels, that's okay too, but Buffy states that she does not agree with Tara on that point because that would mean that she is just using Spike. Caught between the unsavoriness of either loving Spike or using Spike, Buffy begins to desperately plead for something to be "wrong" with her so that she can blame her "wrongness" for how she feels about Spike, what she does with Spike and for how she treats him and for how she lets him treat her. She breaks down crying in Tara's lap, unable to accept that she's actively decided to love or to use Spike.
