Eric (John White), who participated in the streaking convention in the fifth film, is promoted to DeWitt's university as he wished, but he is depressed because he was dumped by his girlfriend. His father even gave up his "peach list" from his youth. To cheer him up. College life, where men and women share bathrooms, is indeed crazy. Moreover, the Beta Brotherhood club led by DeWitt regularly holds carnival parties, which alleviates Eric's depression. However, Beta Brothers is facing the impact of the "GEK" fraternity founded by a group of elite people in the school, and Eric and others are also preparing to join the fifty challenges Beta has experienced. While Eric was immersed in tasks, the conflict between Beta and GEK continued to escalate, and finally developed to the point that the "Ancient Greek Games", which had been banned by the school for 40 years, would the Brotherhood regain its glory?
