Plot Synopsis

Twenty-five-year-old Jennifer Mills lives her life without commitments -- she is relieved that her boyfriend isn't even close to putting a ring on her finger. Not at all like her older sister, Mandy, who married young and settled into family life; she loves being carefree. But her mother, Kathryn, sees Jennifer's wild ways as a fear of settling down, and hatches a secret plan to change all that. When Mandy and her husband plan a three-week vacation without their three kids, Kathryn convinces Jennifer to help watch them until she can get into town. Jennifer quickly finds out playing house isn't easy. She soon realizes she has to go from cool aunt to strict parent if she's going to keep her sister's trust. But, with a little help from Will, the handsome new neighbor across the street, she manages to pull it together to prove to everyone -- and even herself -- that taking responsibility can be rewarding.
