Ralph enters the school dance, where Richie and Richie unsuccessfully try to get girls, observing "Bag" Zombroni of the Demons gang having greater success. Potsie suggests they try to join the gang, pointing out that Fonzie used to be a member.
Fonzie struggles to start his bike as Richie and Potsie approach him to ask about joining the Demons. He reluctantly agrees to help them.
Fonzie attends the Demons initiation with Richie and Potsie. They both make it past the first stage, then say they must do the "deadly dares" in order to be members.
At Arnold's, they are dared to make juvenile crank calls and kiss Marsha. They then are dared to roller skate through the hallway at school, stealing a teacher's toupee in the process. At the movie theater, they are dared to sing "My Country, 'Tis of Thee" in a screening room where Richie's family are present.
Howard gets a headache and at home, he suggests to Richie that the girls who fall for Demons may not be worth it. Later at Arnold's, as another dare, they tie a police officer's shoelaces together as he speaks to Marsha and plans a date with her. However, this is ruined when the officer falls on her and she thinks he is assaulting her.
The final dare for the boys to become Demons is to go to a school dance dressed as girls. Fonzie dances with Richie and when he learns that "she" is Richie, he claims to have known the whole time and was trying to help him.
Richie and Potsie later decide that they do not really want to be Demons, reflecting Howard's advice.
