Two celebrities are unprepared for the surprise demands of pregnancy; hormones wreak havoc on a baby-crazy author, while her husband tries not to be outdone by his father, who's expecting twins with his young trophy wife; a photographer's husband isn't sure about his wife's adoption plans; a one-time hook-up results in a surprise pregnancy for rival food-truck owners.

Sarah Thompson, an American visiting England, meets and marries William Whitfield, the Duke of Whitfield. They settle in a chateau in France and begin a family. World War II interrupts their happiness and alters their future. After the war, the family helps war survivors by buying their jewelry and eventually opens a jewelry store, which rapidly becomes a success. But conflicts abound as new generations arise and forces from both outside and within threaten the store and the family.

Eustace, along with a new companion named Jill Pole, is brought back to Narnia. The pair are told by Aslan they must search for King Caspian's missing son, Prince Rilian.

Eustace is sent to a horrible school and finds a friend in Jill Pole, who's also running from bullies and looking for a place to hide. The two of them are magically transported from the garden shed into the magical world of Narnia, where they are entrusted with a task by Aslan: to rescue the king's stolen son, Prince Rilian. Together with Puddleglum the Marshwiggle, they must travel north across the mountains, dodge giants, and journey down into the earth itself to rescue Rilian from the mysterious evil that holds him bound there.

Young Prince Caspian of Narnia wonders and dreams about the old days of Narnia when animals talked, and there were mythical creatures and four rulers in Cair Paravel. But his uncle and aunt don’t like to hear him thinking of such things, and plan to murder him and take his throne. Caspian’s tutor, Dr. Cornelius manages to save him, and not only teach him about the old ways, but bring him into the real Narnia and introduce him to the real Narnia. But Caspian’s plight is desperate, and he must use the legendary horn to call help from another world: Peter, Susan, Edmund, and Lucy. Then, Lucy and Edmund are sent back to Narnia, along with their cousin Eustace, to assist Caspian on a voyage. Along their journey the children battle dragons and sea serpents, and sail across a golden lake to reach the edge of the world.

Peter, Susan, Edmund and Lucy are evacuated from London at the beginning of the Second World War, little dreaming of the magical adventures that lie ahead.
