A couple raise 12 children who are involved in music, dance, and wrestling in Nashville, Tennessee. Brenda's birthday is coming up, but she's so busy with the kids' lives that it's in danger of being forgotten until Jessica writes a song called "Mama," which their band perform later at the Grand Ole Opry in Nashville. Also, the family helps raise money for a community charity with a concert at a local library.

A Grand Ole Opry opportunity to perform with country star Josh Turner catches the family by surprise, so they scramble to create a dance routine and choose a song while dealing with wardrobe malfunctions before the gig.

Jair gets ready to propose to his girlfriend, Mary, and his sisters are eager to help. Meanwhile, the younger kids recreate a winning dance routine their older siblings did years ago.

New musical performances help the family get in touch with their Irish roots

Brenda and Toby's romantic dinner is interrupted by Jaeger. Later, Jessica and Jair go to New York with their mother to shoot a music video and meet with a record executive, while Toby stays at home with the other 10 kids.

A month-long tour includes rock climbing in Minnesota, wrestling in Colorado, and surfing on the West Coast, but the kids must also find time for schoolwork and interviews in between gigs.

The cross-country tour ends, but now the family prepares for their album-release party.
