But Lucia is determined to fight injustice and escapes with Oscar to prove his innocence by finding the real thief. Soon they are facing the secret brotherhood of The Grey Monks, who have sworn to destroy the crystal and end Christmas as we know it. And Lucia realizes that there is more at stake than she thought. Lucia and Oscar have to fight the brotherhood for the crystal all the way into the dangerous.
