Annie Cassidy has always had a simple life. She lived with her mom, dad, and her twin brother, Austin. She's always been close to each of them, a bond nobody could break. Except that one fatal night, when her parents were killed in a head-on collision. Her and Austin have no other family, and are taken under the wing of their father's best friend, Derek Emerson. Annie and Austin are moved from a small town in Indiana, to the giant city of Los Angeles, California. But, what Annie and Austin don't know, is that Derek has seven kids. And they're all boys.
