How Long Is “Yoga”?

Six women seeking physical perfection join a mysterious yoga studio owned by a woman who claims to possess the secret to eternal beauty. When home shopping network personality Hyo-Jung begins to fear that she is about to get edged out by a younger, prettier host, she begins searching in desperation for a way to stay beautiful. As if by fate, Hyo-Jung soon has a chance run-in with her former classmate Sun-Hwa, who has miraculously transformed from a homely student into a beautiful woman. Sun-Hwa refers Hyo-Jung to Mihi Khan's Yoga Academy, where she claims that any woman can achieve the same results under the tutelage of impossibly gorgeous yoga master Nani. But flawless beauty comes at a high price, and in order to get it, Hyo-Jung and her fellow students must follow a strict set of rules. When the rules start getting broken and students start to disappear, Hyo-Jung realizes that something sinister is going on behind the scenes at the academy.
