Watch Longtake Onetake Mistake (2026) Official Trailer

Actor Lee Yong fails even his thousandth audition. Just as he is about to give up on everything, a flyer catches his eye: "7 Days Until Submission Deadline for the Bucheon International Fantastic Film Festival." He seeks out Chang-kyung, a former film director living in seclusion after a devastating failure, and proposes a reckless plan — to make a film in just seven days. With no budget, no crew, and no future, wounded souls begin gathering one by one. Soon, the bizarre filming of a period fantasy begins: a woodcutter turned into a bloodthirsty monster and a fairy transformed into a ghost bride.
