The Antique Gift Shop (2004)

Blurb:
Did you know that an antique possesses a soul of its own? The Antique Gift Shop specializes in such items that charm and captivate the buyers that they are destined to belong to. Guided by a mysterious and charismatic shopkeeper, the enchanted relics lead their new owners on a journey into the alternate cosmic universe to their true destinies. Eerily bittersweet and dolefully melancholy, the Antique Gift Shop opens up a portal to a world where torn lovers unite, broken friendships are mended, and regrets are resolved. Do you believe?
