Synopsis
A satirical series that closely looks at the materialistic desires of the upper-class parents in South Korea and how they ruthlessly secure the successes of their families at the cost of destroying others' lives. The drama revolves around the lives of housewives residing in a luxurious residential area called SKY Castle in suburban Seoul, where wealthy doctors and professors live. The wives are determined to make their husbands more successful and to raise their children to be top students, who will be accepted at the best universities, so they use every possible way to get that.
Han Seo-jin (Yum Jung-ah) is married to an ambitious doctor, Kang Joon-sang (Jung Joon-ho). She wants her eldest daughter, Kang Ye-seo (Kim Hye-yoon), to also become a doctor. In order to do that, she hires Kim Joo-young (Kim Seo-hyung), a coordinator with an one hundred percent success rate when it comes to her students' admission to the Seoul National University.
No Seung-hye (Yoon Se-ah) is the wife of Cha Min-hyuk (Kim Byung-chul), a perfectionist law professor. She does not like the way her husband teaches their twin sons, Cha Seo-joon (Kim Dong-hee) and Cha Ki-joon (Jo Byeong-kyu). Later it is revealed that their daughter, Cha Se-ri (Park Yoo-na), who has always been Min-hyuk's pride since she attends Harvard University, hides something from them.
Jin Jin-hee (Oh Na-ra) is the mother of Woo Soo-han (Lee Eugene). She wants her son to be like her husband, Woo Yang-woo (Jo Jae-yoon), which means becoming a doctor. She befriends Seo-jin to get information and to achieve a perfect career and education for her family.
Following the suicide of Lee Myung-joo (Kim Jung-nan), mother of Park Young-jae (Song Geon-hee), who was a former student of Joo-young and recently admitted to the Seoul National University, Lee Soo-im (Lee Tae-ran)'s family moves into the SKY Castle. Her husband, Hwang Chi-young (Choi Won-young), works at the same hospital as Joon-sang and Yang-woo and her son, Hwang Woo-joo (Kang Chan-hee), attends the same school as Ye-seo. Her family often clashes with the other residents due to their differences in opinions.
