It is 1930s Australia, and clergyman Anthony Campion (Hugh Grant) has arrived from England with his wife Estella (Tara Fitzgerald) to find a scandal brewing. Painter Norman Lindsay (Sam Neill) is exhibiting a picture that has outraged the church establishment, and Anthony is asked to visit the painter and negotiate its withdrawal. The couple spend several days with the Lindsay family and three free-spirited models (Elle MacPherson, Kate Fischer and Portia De Rossi) who are posing for a nude painting of the legendary Sirens. As Anthony debates with Norman, he is shocked to realise his wife is being drawn into the seductive games of the three sirens.
