The player takes the role of Giana (referred to as Gianna in the scrolling intro and also the intended name before a typo was made on the cover art and the developers just went with that rather than having the cover remade), a girl who suffers from a nightmare, in which she travels through 32 dungeons full of monsters, while collecting ominous diamonds and looking for her sister Maria. If the player wins the final battle, Giana will be awakened by her sister.
