What's The Defects all about?
At the heart of the series is Kim Se Hee (played by Yum Jung Ah). She's the chief director of a prestigious hospital and a philanthropist known for her charity foundation. But behind her angelic public image lies a horrifying secret. She's the mastermind behind an underground illegal adoption ring, operated in part by Jung Hyeon (played by Dex).
Kim Se Hee believes only children with "superior genes" deserve to live and thrive. When adopted children don't meet expectations, they're returned. And when they're returned, they're eliminated; murdered to erase any evidence of the operation.
Among those discarded was Kim Ah Hyeon (played by Won Jin Ah), a child who miraculously survived the organization's brutality. Now grown, she leads the defective children in a rebellion against their tormentors. She's determined to take down Kim Se Hee and expose the truth.
