由朴艺荣领衔主演的玉贞姐姐是一部综合评分6.0的韩国电影。讲述了Yujeong, who works as a night shift nurse at a general hospital's cardiology department, is now told that her 12th-grade younger sister, Kijeong, has been arrested by the police as a suspect in an infant abandonment case. Only then does Yujeong start to make desperate efforts to rescue her sister.  算是能看，但剧情略显拖沓，好在演员阵容强大，多少弥补了一些不足。
