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. 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.
