What is Winter's elaborate plan to celebrate her seventeenth birthday?

Winter's elaborate plan to celebrate her seventeenth birthday starts with convincing her mother to let Winter drive her to the mall for a shopping trip. Once she has convinced her mother that she can drive the car, she invents a Long Island friend and tells her parents that she is attending a party at Hofstra University. She drives her mother's red Mercedes to pick up her friend Natalie and two young men. She takes them to the Marriott for a wild night of drink, drugs, and sex.
