In this Tony Award-winning musical by Stephen Sondheim, several fairy tale characters learn the hard way that the 'Happily Ever After' they sought isn't necessarily so happy after all.
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.
