人过中年的千叶厚志（温水洋一 饰）曾经是小有名气的漫画家，然而他的生活江河日下，加上他无心上进，沉湎赌博玩乐，以致于妻子阳子带着女儿友理离开。千叶则过着债台高筑的生活，日常里被高利贷恐吓追讨，惶惶不可终日。这一天，千叶从昏迷中醒来，发现自己脑袋上罩着塑料袋，被人捆绑囚禁于一个集装箱内。他费尽力气挣脱束缚，报警无人理睬，逃生则找不到出口。究竟是何人为了什么囚禁他，千叶毫无头绪。不久后他发现，周围似乎还有很多集装箱，许许多多人也遭到非法囚禁，而且总数竟然多达数百人。他和其他落难者交流信息，结果发现了他们之间的共同点。

Mister Chiba awakens in a container, tied up with a plastic bag over his head. When he manages to free himself, he finds a mobile phone, a light stick and a strange black stone. A number is tattooed on the inside of his wrist. From the way the container shakes can be deduced that Chiba is transported first in a truck and then on a ship. And he’s not the only one. People are trapped in the containers next to him as well, about a hundred in total. What is the purpose of this forced journey?
