The Heirs

The Heirs" depicts the friendships, rivalries and love lives of young, rich heirs led by Kim Tan (Lee Min-Ho) and a girl named Cha Eun-Sang (Park Shin-Hye). Unlike the others, Cha Eun-Sang is considered ordinary and comes from a poor background. 18-year-old Cha Eun-Sang lives with her mother who is mute. Her mother works as a housekeeper and Eun-Sang also works part-time jobs to help out. One day, Eun-Sang's older sister (Yoon Jin-Seo) calls from the U.S. and informs them that she will marry. Eun-Sang's mother then asks Eun-Sang to send her older sister some money from her savings account. Eun-Sang isn't happy with her situation and decides to go to the U.S. herself to see if she can start a better life with her sister. Source: AsianWiki
