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.

Ronnie Anne makes friends with Sid, a girl whose family wants to rent the apartment upstairs; when it looks like another couple might get it first, the girls resort to sabotage to try and dissuade them.

Lincoln and Clyde worry that they may be too old to still be playing Ace Savvy; Lincoln discovers that having a friend over means getting special privileges, and he takes advantage of that.

Lincoln and Clyde's spring break plans are put in jeopardy when they only have one day to complete their list; Lori throws a sophisticated party, but it backfires when her guests do not like what she has planned.

Lincoln has a plan for introducing himself to a new girl; Pop Pop introduces his new girlfriend to the family; she seems great until she starts showing up unannounced.
