Mrs. Krabappel's class is going on a field trip to the Springfield Nuclear Power Plant, but the bus is late. When Otto arrives, Bart has to sit with Wendell (much to his dislike) because of talking with Otto about his new tattoo. Once on the bus, Mrs. Krabappel tells the students not to stick any part of their body out the window, reminding them of the story of the boy who stuck his arm out the window to have ripped off by an oncoming truck, Bart stands up with his arm in his shirt and says,"And I was that boy." After driving for a while, the bus passes the school again, Mrs. Krabappel asks Otto if he knows where they're going, and he says it's a shortcut.
When they finally arrive, Smithers gives the kids a tour throughout the plant and explains them what the nuclear power is. Sherri and Terri tell Bart that their father also works at the plant with Bart's dad, and that he says that Homer is incompetent. Bart is confused by the word and they explain that it means that Homer is unable to do is job right, and Bart replies,"That's a relief, I thought you were putting him down." Bart spots Homer at work and calls out to him. As Homer looks up to wave back at Bart he crashes the cart he was driving into a pipe, causing it to leak dangerous gas and Homer to get fired.
The next day, he looks for another job, but he is not accepted at any of the possible jobs. At night, trying to find a beer, but having none, Homer goes to buy a pack, but unfortunately he has no money and as a last resort, he breaks Bart's piggy bank. Realizing what he has just done is wrong, he goes out while his family is sleeping, picks up a rock and goes to a bridge attempting to kill himself.
His family comes and is almost hit by a car, but Homer manages to push them away from the road just before the car reaches them. This makes Homer decide to get a stop sign on the dangerous intersection. His proposition is accepted, so he starts to do more public safety things for the city. He becomes a public safety advocate and installs speed bumps on roads, speed limits, danger signs (like a dip sign), and so the city finally gets full of signs, like the park, which is full of "no stepping on the grass" signs.
Homer later decides to go to the real problem: the power plant. All the citizens support Homer with his demands, but Mr. Burns is against him. While Homer is on his car in front of the power plant speaking through a megaphone, Mr. Burns calls him to his office and proposes him a job as the safety inspector of the power plant. As this will help with the city's safety, Homer eventually accepts the raise and informs the people. After his celebrating dancing, he falls from the balcony and the citizens catch him and carry him while cheering.
