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.

When Dad gets upset with the children for never locking the front door, they decide to take home security to the next level; when Lincoln accidentally erases his childhood photos, he and Clyde attempt to recreate them before his memory fades.

When Lola advances to a regional pageant she worries she could lose for the first time; Dad has Mr. Grouse watch Lily while he goes to a concert, but things quickly start to go wrong.

Luan mentors Lucy, teaching her how to manage the ups and downs of pursuing a life in the arts.

Mom takes over when Lucy quits the writing club at school due to the by-the-book way Huggins runs the club; Luna and Sam embark on a challenge taking place across Royal Woods and discover they have less in common than they thought.
