In the year 2046, a young woman named Future (Macy Wu) is dispatched to Hong Kong in 2011 by the United Nations. Her mission is to conceive a child so that her genetic material can be used to repopulate the Earth, as 99% of men have become sterile due to attacks from Planet Xucker. To thwart her mission, two assassins from Xucker, Taka Kato and Ya-wen Hseh, are sent to pursue her. During her time in Hong Kong, Future encounters three university students: Felix (Justin Cheung), Dan-san (Andrew Kwok), and Sing (Tsui Ho-cheong). These men are infatuated with their female neighbors: Chin-chin (Akiho Yoshizawa), Chen-chen (Monna Lam), and Sai-sai (Chen Chih-ying). The students agree to assist Future in finding a suitable partner at the university.
