Elena, an ordinary teenage girl from the modern world, slips down a well and transports to the fantasy realm Adoria. Bound by an ancient Chalice oath, she has to pass six ruthless trials devised by tyrannical Regent Marcus. Each trial sends a deceptive noble suitor to lure and destroy her with fake affection, power plays or feigned misery. Lieutenant Cain, a scarred silent knight, swears full protection yet obeys a rigid rule to stay three paces from her. He silently witnesses every trap and endures endless pain for her. Elena unravels all layers of conspiracy one by one, defeats Marcus in a final combat, and confronts his hidden nephew Cassius later. She ultimately claims the crown, establishes humanitarian decrees in memory of the six tragic young men, and unites with Cain, the quiet guardian who has loved her through all hardships.
