Claire Wang is a "parachute," a wealthy teenager from Shanghai sent to the United States to live with a host family and attend a prestigious high school. Dani De La Cruz is Claire's host sister and attends the same high school on scholarship. She resents the privilege of students like Claire, while she cleans houses part-time and works for every success she attains. Both girls merely tolerate each other, until a series of traumatic events caused by male counterparts bring them together.
