The Sacrifice

It is Otto's birthday, and his family have gathered at his remote cottage to celebrate. The celebrations are marred, however, first by conventional family intrigue, then by the terrifying news that the low-flying jet planes signalled the start of a nuclear war between the superpowers. As the family attempts to cope, Otto is troubled by extraordinary dreams, and then informed by the unfathomable philosopher-postman Victor that he has the power to redeem the world, including his dear infant son, if only he will visit the solitary Anna, who Victor insists is a witch.
