1951. Among the coppiced carob trees and arum lilies of the Barossa Valley, old-school Lutheran William Miller lives a quiet life with his wife, Bluma, and son, Nathan, making wine and baking bread. But William has a secret. He's been studying the Bible and he's found what a thousand others couldn't: the date of the Apocalypse. William sets out to convince his neighbours that they need to join him in preparation for the End. Arthur Blessitt, a Valley pioneer in floriculture, helps William deliver pamphlets and organise rallies. Others join the group but as the day approaches their faith is tested. The locals of Tanunda become divided. Did William really hear God's voice on the Hill of Grace? Did God tell him to preach the End of Days? Or is William really deluded? The greatest test of all for William is whether Bluma and Nathan will support him. As the seasons pass in the Valley, as the vines flower and fruit and lose their leaves, William himself is forced to question his own beliefs and the price he's willing to pay for them.
