After years of living apart, Backstreet Boy Nick Carter reunites with his younger siblings by inviting them to live together with him in his L.A. mansion in order to repair their fractured family.

Nick's reaction to bad news about his mother upsets his siblings; later, a disagreement about Aaron's loud music turns into a physical confrontation between Nick and Aaron.

After Aaron throws a wild party in the house, big brother Nick decides to lay down the line. Meanwhile, B.J. realizes she's fallen out of love with her boyfriend but doesn't quite know how to break it to him.

The Carter kids pursue their separate career goals: Nick and Aaron launch their own record label, Angel tries to make it as a model, Leslie pursues singing/songwriting while B.J. gets a a job at a restaurant, working under a chef.

Feeling estranged from her family, middle sister Leslie clashes with her sisters as she struggles to find her place within the Carters and be loved.

The Carters' plans for a family vacation in San Diego are marred when Aaron lands in the hospital after a surfing accident.

After the Carters seek group therapy to deal with their family dysfunction, they get a visit from their long-lost dad, Bob, who is given a cool reception by an emotional Leslie.

As the summer ends and the Carters prepare to go their separate ways, B.J.'s reconciliation with her ex-boyfriend Wes is hindered by her drinking problem and by little brother Aaron's unwelcome involvement.
