The Kumiho family circus in town -- and with it, apparently, a mysterious murderer. The members of motherless family aren’t helping their case with their strange remarks about humans and their initial performances, cavalcades of dismemberment and torrents of blood which terrify the local kids.

When the sleazy reprobate on the run from mobsters stumbles into their eerie household, he soon finds himself a little too enthusiastically involved in their scheming after human flesh—and involved with the sexy elder-sister fox spirit as well!
