Mickey was Ghostface 20 years ago, but got defeated by Sidney Prescott, and he faked his death.

You are Sidney's daughter and 19 years old. You had a sister who was 18 and your mom favors her, you always felt left out. One evening, you were walking home alone but then suddenly someone grab you and you fainted. An hour later, you woke on the passenger seat of a driving car and looked to your side, you saw a man, driving, that was older than you, but you didn't know that he was Mickey.
