Buffy feels life getting on top of her with Willow calming down after an incident involving Dawn, a car and Willow high on the magicks (so much so that her eyes are almost permanently big and black). Dawn is ignoring Buffy too. The reason for that is because Buffy wasn't around (having sex with Spike) and is only talking to Xander. The social worker comes round to check on how Buffy's doing (at the worst possible time). The living room is scattered with Willow's old spell ingredients and objects. Buffy digs herself into a deep hole by saying "It's magic weed." Spike, in the daytime but using a blanket to cover him, comes over to her house wanting his lighter back. Then he leaves, calling Buffy Goldilocks. Meanwhile, Warren modifies his freeze ray into an invisibility gun.
In a state of depression, Buffy cuts most of her own hair off, resulting in her visiting the hairdresser asking the hairdresser to please fix it. As she leaves, the Trio pulls up to a tanning salon nearby, about to make themselves invisible. However, Andrew and Johnathan fight over who is going to use the gun first and accidentally overload it, sending beams over the parking lot; a beam hits Buffy, making her vanish (along with a dumpster, traffic cone, and fire hydrant).
Anya and Xander are talking about their upcoming wedding at the Magic Box. The door opens but no-one enters. Buffy's voice comes out of nowhere, along with picking up two magical circular items and making them look like eyes. Buffy continues her invisible adventures in Sunnydale. "I'm the ghost of fashion victims past," she moans to a civilian, who is wearing a studded cap. She then drives off with a parking inspector's van.
Buffy drives to the workplace of the social worker who had made that morning's inspection to the Summers' home. Using her invisibility to its full advantage, she tricks the social worker into behaving in a bizarre manner and replaces the Summers' report with pages consisting entirely of repetitions of "All work and no play make [sic] Doris a dull girl", an allusion to The Shining. She also tells her supervisor that "There was a voice. It made my coffee dance". The woman's supervisor believes that she is having a mental break with reality and sends her home, saying that he would send someone else to inspect the Summers' home the next day.
She then heads to Spike's. Buffy attempts to sexually assault Spike, before he realizes who she is. "I told you to stop trying to see me," she finally jokes and then she and Spike go underground for sex. In the meantime, Xander and Anya discover that the invisibility ray was causing the structure of the traffic cone to break down, and realize that the same thing would happen to Buffy if the invisibility wasn't reversed. Xander runs to Spike's crypt in search of Buffy, where he finds Spike in bed, naked and apparently alone, "doing push-ups". Xander has a chat with Spike, wanting to know where Buffy is, and Spike honestly says that he hasn't "seen" her. Throughout the conversation, invisible Buffy gropes and physically teases Spike, causing him to feel pleasure in Xander's presence. Spike tries to act normal, somewhat unsuccessfully. Xander finally leaves, disgusted by Spike's odd behavior, telling Spike that he really needs to get a girlfriend.
Buffy wants to continue their physical activities, but Spike tells her that he is tired of being with her and not really having her. He asks her to leave if she isn't really going to be with him. He is frustrated with her carefree attitude and doesn't appreciate the way she seems to be using the invisibility as an excuse to escape her real life. She protests, but eventually leaves. She doesn't do too well at home when she scares Dawn, who has the same frustrations as Spike, combined with extreme worry for her sister. The bad stuff keeps on coming when she gets the message from Xander and Anya on the answering machine. "Tell her about the pudding" says Anya, referencing the way the invisible traffic cone found by Willow had started to disintegrate into mush. However, before Buffy can head back to the Magic Box, Jonathan phones her up (disguising his voice so Buffy doesn't identify him) and tells her that the Trio has kidnapped Willow and tells her to meet them at the arcade.
Buffy does so. However, Jonathan, Andrew, and Warren Mears have also made themselves invisible, and Warren is holding Willow hostage. Warren lies to Buffy, telling her that he is going to reverse the mechanism into making her visible. But Willow points out that he's put it on a setting that is going to kill her. Warren knocks her to the ground and aims the gun at Buffy, telling her that she can't see them. However, Buffy's Slayer training (and possibly her experiences in "Out of Mind, Out of Sight" and "Family") provide her with some ability to sense the invisible villains. A scuffle ensues. Warren ends up in the ball-pit, Andrew ends up in the pinball machine and Buffy is holding Jonathan. Willow, who has changed the frequency, aims at Buffy, Jonathan, Andrew, and Warren. "So, you three have what? Banded together to be pains in my ass?" Buffy asks. Warren stands firm. "We're your arch-nemesises... -ses." After a smoke-bomb goes off and after scuffling to open the door, the Trio escape. Buffy and Willow sit on the curb outside and talk. "You've cut your hair," observes Willow. The two then discuss the events of the day, and Willow admits she nearly used magic but didn't, Buffy also admits that while she's still not happy about being alive, when faced with death she realised she didn't want to die. The two then contemplate their small but notable steps towards dealing with their respective problems.
