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.

When the Loud parents win a trip to a resort, they decide to take the children with them because the children have promised to behave; when Lucy gets a crush on a "regular and normal" boy, her sisters decide to give her a makeover.

The Louds team up with the Casagrandes for a Halloween storefront decorating competition, but things get out of hand when they use Lucy's spell book to make the mercado extra spooky.

Luna and the Moon Goats have to find a replacement guitarist for the band when Luna injures her hands from playing; to make it to Udder Madness Day at Dairyland, Lincoln is determined to get laundry duty finished quickly.
