Not long after the events of Professor Layton and the Curious Village, archaeologist and puzzle master Professor Layton and his young apprentice Luke Triton reminisce over one of their earliest adventures together from three years ago: Layton is invited by his former student Janice Quatlane to watch her perform in an opera at the Crown Petone opera house, which is built on the White Cliffs of Dover. The performance centers on the legendary lost land of Ambrosia and the secret of eternal life it holds, which will be rediscovered when its queen returns. Janice believes recent strange occurrences are somehow connected to the opera: girls have disappeared from London and the opera's composer, Oswald Whistler, has recently adopted a young girl who has claimed to be his deceased daughter Melina. Whistler plays the entire opera on the Detragon, an elaborate one-man orchestra machine. Once the performance is complete, a mystery man informs the audience that they are to play a game, the winner of which will receive the secret of eternal life.
