It is a teaching assistant's last day in Mr. Van Dreissen's class. Before she leaves, she criticizes the rampant sexism displayed by the class' students and invites them to the next Sisters of the Highland Society for Womyn seminar at the community center, noting it will give them a chance to meet feminist leaders who oppose prostitution and "offer their services to the community strictly for free". Beavis and Butt-Head, being their usual selves, hear the words "prostitute" and "free" and decide to attend.
At the seminar, Van Dreissen's assistant, also the lead speaker at the meeting, announces a grassroots campaign to have the spelling of "women" changed to "womyn," claiming the current spelling implies women are merely a subset of men. Meanwhile, Beavis and Butt-head arrive and suprisingly notice the word "womyn" on the sign posted on the door. Concluding that it is a typo, they report this "misspelling" to the receptionist on their way inside.
Upon entering, Butt-head calls the feminists in attendance "sluts". The speaker notices Beavis and Butt-head's presence and praises them for seemingly "joining them in [their] fight against the patriarchy". As the women applaud, Beavis and Butt-head assume they are clapping because they "want" them.
Beavis soon notices he and Butt-head are the only males in the room, pointing out that if this is a free prostitution event, there should be more men. Butt-head dismisses him and attempts to solicit sex from the woman to his right, calling her a "chick". She calls him a jerk and storms off. Butt-head tells Beavis she was "playing hard to get," only for Beavis to point out two other women nearby. Beavis misreads the red-haired woman's T-shirt as "women right now", then sexually harasses her and gets a face full of mace. Butt-head then tries to seduce the brown-haired woman, and she begins to beat him up. Subsequently, all the feminists in the room dogpile on both of them.
At home, the two, now covered in bandages, watch the news report of the incident on TV. The reporter thanks God that the feminists have learned that male chauvinism is best handled with "fanatical violence". Beavis starts twitching at the word "violence," but the movement makes his injuries hurt more. Butt-head tells Beavis how he got to touch a woman's boobs during the beatdown, and Beavis notes that one of them touched his "nads" with her fist. Despite what happened, they decide they must come back next time.
