Rural Cyprus, 1925. Despo is recently married, heavily pregnant and deeply afraid. The twelve days of Christmas are beginning - the time when, according to local folklore, creatures known as kalikantzari come up from Hell to wreak havoc.

Meanwhile, her husband Loukas has troubles of his own. Struggling with dreams and desires he doesn't understand, he finds himself irresistibly drawn to an Englishman, a newcomer to the island. In a village wreathed in superstition, Despo and Loukas must protect themselves and their unborn child from ominous forces at play.
