A twenty-first century woman is stranded in first century Pompeii when a time travel experiment goes awry; she is sold to a wealthy family as a house slave. This provides her with an intimate, upstairs/downstairs perspective on household life in ancient times. At first she does menial work, but she improves her situation by telling stories and making prophecies. As her influence grows, she wins the love of her master and his daughter and provokes the vengeful jealousy of his wife.
