As they watch the news about a murder at an apartment, Beavis and Butt-head decide to go there, but to make matters worse, Butt-head won't stop calling Beavis a "buttknocker", and thus leads Beavis on the verge to kill Butt-head, and caught by the police.
Beavis and Butt-head are at home watching the nightly news. There is a report of a man who murdered his brother in an apartment not far from the duo's house, so they decide to go check it out. On their way there, they speculate as to why the man killed his brother. This leads Butt-head to start calling Beavis a "buttknocker", a name that enrages Beavis. Finally, the two reach the apartment building. They move the police tape out of the way and head into the room, where the body of the murder victim has been marked out on the floor. The two begin wondering how the man was murdered, and Butt-head starts calling Beavis a buttknocker again. Beavis gets so mad that he tries to kill Butt-head and they get into a fight, and after some tussling, Butt-head is laying on his back in the outline of the victim's body. Before Beavis can strangle him to death for refusing to stop calling him a buttknocker, the police storms the apartment and take Beavis into custody. At the police station, Beavis is placed in the same cell as the man who was reported to have killed his brother, and they relate to each other. Butt-head selects Beavis from a lineup of suspects, but he refuses to press charges, saying he will simply kick Beavis's ass later as punishment.
