Move in with her straitlaced sister and wreak havoc, that's what! Shooting star Amanda Bynes (What a Girl Wants, All That) runs wild in this lively comedy.

Although she misses Dad, free-spirited Holly (Bynes) idolizes her big sister, Valerie (Jennie Garth - Beverly Hills 90210), a promising public relations upstart with a tidy little place in Manhattan.

With Holly's antics turning Valerie's regimented life upside down, it's a good thing these mismatched siblings love each other--or they'd go crazy in no time!
