Kate Leslie, a widow of forty with a mind of her own, visits Mexico. There she becomes involved

in a subterranean world of primitive gods and mystic ritual. And between her and Cipriano, one of the leaders of a revolutionary religous movement,

springs a violent paradox of love. Hostile and indifferent as she is to the cult of the Plumed Serpent,

Kate finds through it a revelation which is decisive to her fulfilment.
