After realizing she may want to date women, Anna goes to her roommate's cousin's lesbian engagement party in the hopes of finding answers, but discovers something much more terrifying instead.

Like the original film, the sequel is set in a near future where all drinking and drugs are banned except for on one glorious day known as The Binge. This year, that day happens to miraculously land on Christmas.

故事设定在酒精和毒品皆违法的时代，The Binge Day是所有人都能彻底放松的特赦日。
