On New Year's Eve's night, Avanti, a high-end hotel in Tokyo, entered the most tense and busy moment, and the countdown party was just around the corner. Deputy manager Heiji Xintang (General Secretary of Service), Shintang's assistant Takeshiko Takamoto (Keiko Toda), cleaning woman Takamoto Hashimoto (Matsuko Matsuko), hotel handyman Kenji Nobuji (Xiangzu Shinji), and so on, regardless of the position, all the staff are ready without stop. At the same time, scandal-ridden congressman Fujita (Sato Hiroshi), the couple unexpectedly encountered guests such as zoologist Horida (Takeshi Kono), a zoologist involved with prostitutes, and the stressed singer Su Tokugawa (Toshihiro Nishida), the ventriloquist Sakata, who lost his duck partner and could not perform, continued to enter, plus an endless stream of minor accidents. It makes the Avanti hotel seem particularly noisy. Before the arrival of the New year, the countdown to the hotel's worst two hours begins.
