Perfect Score, Perfect Payback

Stacy Litt is the adopted daughter of the Litt family, and her parents and her three brothers dote on her. Three years ago the family brought their birth daughter, Elsa Litt, back home, and since then all of them have treated Elsa with dislike because of Stacy. On the night after the college entrance exam Stacy hits a girl with her car and leaves her in a coma. Elsa saves the girl, and for that her parents and her three brothers act together and have her sent to a juvenile detention center for the hit-and-run. On the day the exam results are released Elsa walks out for lack of evidence. Her brothers meet her with scorn, and she cuts her ties with the Litts the same day. The results show that she has the highest score in the country, and she uses that to answer the family's contempt at the banquet held for the top scorer.
