So Close to Home (2003)

Maggie, a professional woman dutifully paying a visit to her overbearing mother in Sydney, encounters a 14-year-old Kosovan girl on the train. Strangely propelled by the girl's isolation, she embarks on a mission to reunite her with her mother in a refugee detention centre, but gradually discovers that it is in fact the young stranger who is showing her how to reconcile with her own mother.
