In the middle ages, marriage by proxy was common, but not falling in love with the substitute.
Caroline has found fault with all of her suitors. She thinks she has escaped her duties, until a marriage by proxy arrives. Her future husband is too weak and old to travel. Even the nunnery sounds more appealing than marriage to the old baron.
Nicholas, the proxy, marries Caroline as a stand-in for her new husband. Nicholas, the baron's servant, must help her to fall in love with the baron's character.
When Caroline falls for the proxy instead, what will she do about the baron? Especially, when she becomes pregnant with Nicholas' child?
