Leigh can think of a million ways she'd rather spend a summer besides visiting her movie star mother, Annika. But her dad insists the two need some 'mother/daughter bonding time,' and packs fifteen-year-old Leigh off to Ireland, where she'll be her mom's personal assistant on the set of her latest film, 'Danny Boy.' It could be worse. Leigh's mother may be a distant, self-absorbed diva, but the hot young co-star Sean has a brogue to die for, and things heat up when Leigh lands a bit-part in the movie. Soon, Leigh and Annika are sharing scenes, scripts-and the spotlight-and the leading lady is regarding her daughter's youth and beauty as a threat. With tensions rising on the set, Annika and Leigh must finally grow into their most demanding roles: mother and daughter.
