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 termites infest the house, half the family stays with Pop Pop and the others stay with Aunt Ruth; Lincoln has to complete a woodworking assignment, but has a history of failure on the topic.

Lori takes a job as a waitress at Dad's restaurant, but it turns out that serving is harder than she anticipated; spurred on by a classmate's mocking about Charles, Lana decides to train him to compete in a local dog show.

Clyde discovers he didn't earn junior administrator job, but can't give up the perks that come along with it; when the new girl starts hanging around Lincoln and his friends, they begin to suspect she likes one of them.

When Carol Pingrey's photograph gets more "likes" on social media than Lori's, she tries to one-up her; thinking it looks like fun, the other kids try to get in on Lola's home-schooling.
