At the Springfield Aquarium, Marge accompanies the kids on a school field trip. Lisa spots penguins flying and after Bart has shown off his "flawless pearls," which results in him being taken the hospital, where a lack of insurance card keeps him prisoner. Homer has the insurance card, but is nowhere to be found. As a solution, Homer gets a mobile phone and a few extra unnecessary accessories, which only leads to him not paying attention to where he is driving. That is until it is much too late and he drives off of a pier. Judge Harm takes his license away and Homer is no longer able to drive. Marge picks up the slack and starts becoming "Stresserella." Homer walks to Moe's, but much to Moe's dismay he decide to keep on walking and starts getting healthy. Homer walks to work and is the only employee to arrive, everyone else is caught in a traffic jam. Marge is frazzled from all her driving, meanwhile Homer sings and walks about the virtues of walking when he is stuck by a car; the driver of the car was Marge. Marge, who cares so much for Homer, tries to help in his recovery, but Homer perceives that she might be trying to kill him. It leads to fight, which in turn leads them to see a marriage counselor. After Marge leaves, the counselor suggests that Homer perform one unselfish act of love to win Marge back, in other words take her to dinner. Homer decides to one up that suggestion and invites everyone in Springfield (except the Flanders family) to a backyard barbeque in Marge's honor. Homer joins Jackson Browne in a duet to sing his praises of Marge.
