The real princess grows up scrubbing floors and taking beatings, while the imposter wears silk and a ruby meant for royal blood. Eighteen years later, Elina sneaks out to watch the Royal Tournament. After a horse spooks, Roslyn blames her and has her humiliated. Elina is forced to fight Prince Arthur as a mystery challenger, matching him move for move. Queen Celine recognizes her fighting style. Arthur crowns Elina as queen of beauty instead of Roslyn. Furious, Roslyn accuses her of treason and attempted murder, and the crowd calls for her execution. Arthur draws his sword to protect her.
