Things are crowded in the Loud household, with 11 children -- 10 girls and one boy -- causing craziness in the house. As the only boy, 11-year-old Lincoln is in the middle of all of the chaos. Whether his sisters are giving him unwanted makeovers or he's racing them to the couch to gain control of the TV, Lincoln is often getting involved in antics with his siblings. Lincoln's best friend Clyde, who happens to be an only child, is jealous of Lincoln's large family and is always willing to play his part in the schemes. Clyde has a crush on Lori, Lincoln's oldest sister and self-proclaimed boss, who is dating Bobby, who holds many jobs -- including lifeguard and mall security guard -- even though he's not very smart.

The children give Lily an old singing toy from the attic to help her stop crying, but it quickly drives them crazy; the kids try to convince Dad of the wonders of modern technology after he declares war on their electronic devices.

Luan tries out for the school play to get closer to her crush, Benny; when Clyde and schoolmate Zach begin bonding over a mutual interest in antiques, Lincoln quickly finds himself feeling like a third wheel.

When Clyde thinks that his parents are having another baby, he seeks Lincoln's advice on how to be a big brother; a fight breaks out in the Loud house when Lori and Leni buy identical dresses.

Hoping to win a songwriting contest, Luna contemplates whether she should go with a song that's true to her sound or try to make something that the whole world will love.
