“The Penthouse” is set in a 100-floor luxury penthouse apartment and centers around three women: the “queen” of the penthouse Shim Soo Ryun (Lee Ji Ah), the “prima donna” Chun Seo Jin (Kim So Yeon) who will stop at nothing to get what she wants, and Oh Yoon Hee (Eugene) who will do anything it takes to get into the world of high society.
