The Simpson family has dinner at Greaser's Cafe, a '50s-themed restaurant. While there, Homer and Marge enter a dance contest and win a vintage Harley-Davidson motorcycle. After Bart teaches his father how to ride his new hog, Homer forms a biker gang called the Hell's Satans with Lenny, Carl, Moe and Ned Flanders. While riding around town making trouble, the Satans attract the attention of another, more authentic biker gang who also happen to be called the Hell's Satans. The real biker gang, led by two guys named Meathook and Ramrod, take over the Simpsons' house and trash the place. Marge, ever the gracious host, cooks and cleans for her new guests. When the Satans leave, they take Marge with them. While pursuing the men who kidnapped his wife, Homer goes to Poppa Wheelie's, a biker bar where he sees NRBQ playing. Marge isn't there since she's being held at a campsite by the Hell's Satans. Marge tries to reason with her captors and teaches them that violence is wrong. Just then, Homer arrives to steal her back and winds up battling with Meathook. Luckily, Homer wins the fight and takes his wife home. The Hell's Satans, meanwhile, will take the lessons they learned from Marge and start new, more productive lives.
