Overview
Serpent in the Rainbow is an Australian mini series which first screened on the ABC in 1973. It was set in the late 19th century.
The Bulletin called it "a classical allegory about two squatting families who play out their own version of the Trojan War."
Premise
In outback Australia toward the end of the 19th century, two families that down sheep stations have different views - the austere and religious Quiggs, of "Sinai" station and the more liberal Lovetts, of "Woolumbra".
Helen Quigg leaves her husband, falls for Phillip Lovett and seeks refuge with the Lovetts. The Quiggs want her back but the Lovetts refuse.
