In an old apartment building on the wrong side of the tracks, two women, unknown to each other, live across the hall on the second floor. Galia is an assassin involved against her will with the local sex-traffic mafia. All she wants is to reunite with her little daughter that she left back home in Russia. Eleanor is a grocery store cashier and a battered wife. She dreams of winning the lottery and running away from her abusive husband. Galia and Eleanor don’t know each other, but as neighbors they share two things: an adjoining wall and a strong need to plan their escape. As Galia disobeys her latest contract, a woman target, and Eleanor discovers that she’s pregnant, the two women decide to take action against their oppressors in a fight for survival and freedom.

A young woman named Future (Macy Wu) is sent from the year 2046 to the year 2011 in Hong Kong. Future was sent by the United Nations in order to get pregnant, where she can then extract her genes and repopulate the earth as 99% of males have become infertile in the future due to attacks from Planet Xucker. Two assassins from Xuckler (Taka Kato and Ya-wen Hseh) are sent after her to stop her. Future meets three University students: Felix (Justin Cheung), Dan-san (Andrew Kwok) and Sing (Tsui Ho-cheong). The men are obsessed with female students next door: Chin-chin (Akiho Yoshizawa), Chen-chen (Monna Lam and Sai-sai (Chen Chih-ying). The students agree to help Future find a mate at the university.
