The lives of people in a remote Irish community are upended when their crops start failing after a strange eclipse takes place. One woman, however, seems to have escaped the curse: Agatha. She continues to enjoy abundant harvest even when her neighbors have none. This leads people to believe that she is practicing witchcraft, effectively cutting her off from society. Seventeen years later, the village descends into madness and chaos when it is revealed that Agatha has a daughter—Audrey.
