Based on the Parable of the Hidden Treasure and the Pearl in the Book of Matthew, Chapter
13, versus 44 and 45.

Princess Hope finds a locked golden chest in an empty field.
The evil land owner comes and tells her in not-so-polite terms to get
off his land, not realizing she’s the princess! The golden chest is on
his land and if she wants it, she will have to buy all of his land just
to get the chest. Determined to get the treasure in the chest, she sells
all the things most precious to her at a Courtyard Sale in the castle.
Once she’s sold everything, she’s astonished to learn what she has
sacrificed everything for! With the help of her father, Princess Hope is able to
understand what the real treasure is.
