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.

Luna pranks the entire household every year on April Fools' Day, but this year Lincoln has a plan to avoid her pranks; the Loud children make a trip to the supermarket to do the grocery shopping for their mother, but Lincoln has other plans.

After Lincoln gets a pink hand-me-down bike from Lori, he borrows Lynn's cool BMX bike without telling her; when someone clogs the toilet, Lincoln investigates to find the culprit.

Zach and Rusty fake an alien landing, which sends the whole town on a hunt for little green men; Clyde thinks he's guaranteed the Glee Club solo, until Lincoln accidentally auditions and lands the part.

When the kids break Mom and Dad's priceless vase, they decide the only thing to do is go back in time to their wedding day and prevent them from ever receiving it.
