French aristocrat Philippe de Montfaucon (David Niven) learns bad weather is threatening the crops in his vineyard for the third successive year, and gradually realises he is expected to make the ultimate sacrifice to the grape gods to save them.
Niven and Deborah Kerr (as Phillippe’s wife, Catherine) add considerable authority to the silly premise largely wasting the talents of Donald Pleasence, Flora Robson and Edward Mulhare.
Warlock David Hemmings and witch Sharon Tate have their moments turning a toad into a dove and hypnotising the locals.
The film was controversial in its day and extensively cut for American release.
