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.

For Halloween, Lincoln and Clyde have scoped out a fancy neighborhood to make their dreams of scoring full-size candy bars a reality; Lucy is putting on a haunted maze and the younger girls scheme to get maximum candy.

Lori banishes a ghost she believes is haunting her, but when Fairway's golf team starts to struggle, she realizes she needs to bring it back to turn the team's luck around.

When Stella's music box disappears at school, the gang immediately suspects a student urban legend known as the Rat Beast; after a night of zombie movies, Clyde and Lincoln find an empty Loud house and assume it's a zombie apocalypse.

After agreeing to go to the Royal Woods House of Terror, Lincoln and Clyde have to toughen up and face their fears; Lola discovers that Lucy has an old, fragile doll and decides she must borrow it.
