By Murray McLaughlin. This program is about Pauline Hanson, a former seller of fish 'n' chips and a woman whose politics have divided Australia. Four Corners tests the mood of discontent that Pauline Hanson has tapped into, enabling her in one year to move from the fringes of politics to centre stage. As a voice for those who have been marginalised and alienated, Pauline Hanson is now questioning the political and social basis which has underpinned Australia for the last 20 years.
