Deep within the shadowed and mysterious forests of Transylvania live five sisters; Tati, Jena, Iulia, Paula, and Stela. Each Full Moon the sisters slip through a secret portal into the Other World, where they dance the night away with the place's peculiar but inviting inhabitants. But back in their own world, the sisters' quiet lives are thrown wildly off course as their sickly merchant father leaves for warmer climates during the fierce and bitter Transylvanian winter. Jena is left in charge of the business until he returns. But their cousin Cezar is dubious at Jena's abilities, and begins to strip her of her responsibilities, until the sisters are prisoners in their own home.
