Fonzie finds a note he wrote as a child containing a list of things to accomplish in the next twenty years. On the list is one goal he hasn't yet accomplished: climb Suicide Hill on a motorcycle. The problem is that he's already tried it and failed.

New events in Joanie's life cause Chachi to resent her for not having enough time for him. Each has their own solution: Joanie wants to break up, and Chachi wants to get married.

In an attempt to help Fonzie move on after his break-up with Ashley, Potsie, Chachi, and Roger take him on a retreat to a singles resort. However, to get him to go, they tell him they're going to a sporting camp. When they arrive at the lake, Fonzie discovers what the resort is all about and says he's going to leave. He ends up staying which puts a damper on the rest of the guys' fun.

Richie (with Lori Beth and Richie Jr.) and Ralph return from the army. Howard is able to get Richie an interview with The Milwaukee Journal, but Richie doesn't appear to be interested.

Still upset about having given up on his dream as a screenwriter and having to pretend to be happy all of the time, Richie takes out his frustrations on everyone around him - including punching Fonzie in a bar.

After being nothing more than a coatrack for Fonzie's scarf during a rumble, Chachi enters the city boxing championship tournament to earn his respect. Fonzie is elated when Chachi wins his first fight.

Roger is the new principal of the tough George S. Patton Vocational High School. He thinks he can handle the students there but is sorely mistaken.

Howard decides that it is necessary to build a second bathroom after he's forced to shave at the dining room table. To save money, he decides to allow Fonzie's students to build the room. Howard doesn't realize that the room will take all semester to complete, and this hurts his plan to make a killing in whisper-quiet toilets. He fires Fonzie and the students and says he'll finish the bathroom himself.

Joanie accepts an assistant teaching position at Patton High and immediately encounters trouble when a student has a crush on her.

Chachi is hesitant about asking girls out for fear that he will be rejected. Fonzie tells Chachi that girls will ask him out because he has the Fonzarelli power.

Fonzie meets a beautiful woman, Nancy Haley, at his garage while listening to the radio in a beat-up 1955 Chevy. He takes the woman home, but when he goes back to return her purse, an older woman tells him that the Haleys moved out ten years ago when their daughter was killed in an automobile accident.

Howard is offered the vice-presidential position at a large hardware-store chain and considers taking it and moving to New York. Despite nothing being final and Fonzie feeling as though the Cunninghams are pushing him to leave, he decides to immediately move out of his apartment.

After realizing they're dating people that look like each other, Joanie and Chachi decide to meet in order to explore the option of getting back together. Meanwhile, Fonzie wants to adopt an orphaned boy to whom he's been a Big Brother.

With the recent death of a fellow Leopard Lodge member, Howard fears that he may be ousted as Grand Poohbah for not attracting any new members other than Potsie during his five-year reign.
