Going back to a cave where her sister disappeared ten years earlier, Sarah walks through a portal. A treacherous, king, who happens to be immortal, mistakes her for a runaway princess. She comes up with a plan: pretend to be the princess and marry this king fellow so that she can put on the wedding band that can unlock the portal. Next, search for and find her sister and get the heck out of there as fast as they can. However, assuming the identity of a pricess can have some risky consequences; and getting that ruby ring onto her finger will come at a hefty price.
