Stepmom

Jackie (Susan Sarandon) and Luke Harrison (Ed Harris) are a divorced New York City couple struggling to co-parent their children Anna (Jena Malone) and Ben (Liam Aiken) and help them cope with the change of lifestyle. Luke, an attorney, is living with his girlfriend of one year, Isabel Kelly (Julia Roberts), a successful fashion photographer several years his junior. Isabel, who has never wanted to be a mother, tries hard to make Anna and Ben feel comfortable with her. Anna repeatedly rejects her overtures while Ben, who likes Isabel, adds extra complications with his mischievousness. Isabel behaves with contempt tempered by caution around Jackie, believing Jackie overcompensates for the divorce by spoiling her children.
