Are all participants going crazy? It doesn't matter if you're male, female, single, or married—everyone goes wild! This year again, we're holding an end-of-year party at a private villa with an open-air hot spring, inviting everyone who has taken care of us this year. One of the participants, director Koichi Takahashi, filmed 'Side.A'. Some people joined in despite their confusion, others came full of enthusiasm, and some gathered with ulterior motives... With such a diverse group of participants getting together to drink, of course, nothing is going to stay calm. How will the party, filled with various schemes and desires, end up?
