Goro, a small-time thug who manages an adult video store, is approached with a proposal for a sham marriage. Seeing no option to refuse, he agrees to lend his family registry in exchange for money and the promise that he’d be “helping someone out.” His partner in the marriage is a Chinese woman named Bai Lan, who plans to use the money she earns after obtaining Japanese citizenship to support her family back home. Goro and Bai Lan meet only once, during her immigration screening, after which they each go their separate ways. A while later, Goro receives some unexpected news.
