A senior makes an announcement for prom, while Dahmer's friend is attacked by a bully. At lunch, Dahmer speaks to one of his only friends about a concert of a band they both like. In class the following day, John makes a scene in science class and is forced to sit with Dahmer. Joyce is less than happy, thinking they are rejecting her cooking and lays down the law: "New house rule we eat our mistakes," Joyce says and the dinner continues. David notices that the chicken meat is red (and thus not cooked through) and his father confirms it. His parents ask about tennis, and Dahmer tells him he told them that ended a week ago, but that he is still in marching band. Dahmer asks his father if he could get stronger acid to use and his father says he'll see what he can do. Dahmer tries to take a chicken leg but is told to give it to his brother, despite his preference for dark meat. The dinner is frantic, with everyone talking over each other. Dahmer has dinner with his mother, his father Lionel (Dallas Roberts) and his younger brother David (Liam Koeth). The boys gag and flee, calling Dahmer a freak.
Dahmer then takes one of his jars outside and smashes it on the ground, spraying acid and dissolved animal on the ground. The other boy calls bullshit on Dahmer's claims, saying that the jars probably have nothing but muddy water in them. One of the boys asks him why he does this. He places the cat in the jar and explains to the boys that his father is a chemist, though the acid he has is pretty weak so it will take about a month to dissolve it fully. In a shed on his family's property, we see that Dahmer has plenty of dead animals in jars. They don't believe him, so he says he will show them. They ask what he is going to do with it, and Dahmer replies he is going to dissolve it in acid. Dahmer tells them it is the body of a dead cat and shows them. Dahmer is walking down the road with a bag in his hand, when two kids on bikes come up to him and ask what he has. The man has cerebral palsy and Dahmer begins to imitate him. Arriving home, Dahmer sees his mother, Joyce (Anne Heche) who is talking to an interior decorator that is apparently going to redo their house.

The bus driver sees him and tells him to sit back down. He gets up and stands at the back of the bus and watches the jogger out of the window. On the sidewalk, a man jogs, catching Dahmer's attention. In another row, John "Derf" Backderf (Alex Wolff) is trying to draw the bus driver but is not satisfied with how it turned out. One of the students, Jeffery Dahmer (Ross Lynch) notices and stares at it intently.
As it drives along, it passes some road kill on the street. The synopsis below may give away important plot points.
