The episode begins with Comic Book Guy in aroom with notable amounts of Simpsons memorabilia. He announces that this episode will reveal the fate of Nedna, but that it will be carefully hidden within the episode. He then 'starts' the episode with his computer.
While Homer is arriving at the power plant, he is singing a song in the tune of the Police's Walking on the Moon (words). He finds out the Power Plant hired a new security guard named Wayne Slater who replaced Larry.
Meanwhile, while making crackers for Bart and Lisa, Marge daydreams that she has become a contestant on the cooking show Master Chef. She then wins it and the host, Tom Colicchio, turns into a kitchen. However, when Marge stops daydreaming and gives the crackers to Bart and Lisa, they don't like them as they claim to hate surprises.
Later on, Wayne is walking home in the rain. Homer, who is in a car, offers him a lift and to join Homer at Moe's Tavern for a beer. Wayne refuses at first, but eventually decides to get in the car, telling Homer he seems like a nice guy, and he'll have one drink with him, but nothing else. When Wayne is in the bathroom at Moe's, Snake rushes through the door on his motorcycle to rob the place. As soon as Wayne comes out, he skillfully beats up Snake and stops the robbery. The story spreads quickly and a news segment that features an interview with Wayne with Kent Brockman and an animated Taiwanese dramatization of the incident at the tavern soon airs on television. It is discovered that Wayne was once a highly-trained CIA agent, who decided to go into hiding in Springfield after killing a Ukranian mobster's wife. Throughout the episode Wayne suffers from recurring flashbacks from his previous missions, triggered by unpredictable things, as evidenced when he attacks Mr Burns, resulting in Wayne getting fired.
Homer allows Wayne to stay in Bart's treehouse. Wayne talks in his sleep about a past mission, causing couples in the nearby houses to lose sleep. Ned and Edna are one of these couples, and they are shown holding each other in bed, revealing that 'Nedna' will remain a couple. Unfortunately, news of what happened to Mr. Burns is leaked onto YouTube and viewed by the mobster, named Viktor, in Kiev, The gangster and his henchmen travel to Springfield, kidnap and torture Homer when they find out that Homer is Wayne's friend. Wayne tracks Homer down through a tracking chip he ate unknowingly, frees him and kills all of the Ukrainian gangsters. Afterwards, Wayne decides to leave Springfield, but not before giving Homer the 'fist pound' Homer wanted when they first met at the power plant. However, Marge suggests that Wayne should get a job working alongside her sisters at the Springfield DMV. He decides to do this. At the DMV, when Sideshow Mel requests that his spot be hold while he fetches some papers, Wayne grabs him, stating that no one held his spot when he was a prisoner in North Korea and was forced to write a ridiculous musical play paying tribute to Kim Jong-il while having a car battery hooked up to his nipples.
During the closing credits of the episode, Ned and Edna thank the fans for voting for their relationship to continue. Seymour Skinner then cuts in to ask why he wasn't given a second chance with Edna. His mother Agnes belittles him for attempting the spotlight when the polls are closed and states that she'll never have grandchildren.
