Swallowtail Butterfly (2016)

An industrial section of Japan got the name of “Yentown” as many immigrants come to make money and hope to go home rich. A small group of people in Yentown try to work together to survive—Ageha, a young girl with no family; Glico, a sex worker; Fei Hong, a poor immigrant from Shanghai; Arrow, an ex-boxer from the US; and Ren, a mysterious guy who seems to know too much about guns. Fortune shines upon them when they find a cassette that will get them rich, but along with money, trouble will always follow.
