Vertiginous black and white cinematography assaults the senses as we are drawn into the drama of three individuals high up on a cliff ledge - the infamous 'Gap' in Sydney's harbour. One is there to throw his problems into the sea, the others to talk him down. Last year, director Christina Andreef took the musical form to heady heights with Excursion to the Bridge of Friendship. Her new film is very different - a melding of drama and song that will confront, challenge and divide audiences.
