理央像往常一样驾驶着她心爱的自卸卡车，她对她的伴侣阿修沉迷于赌博、从不支付任何费用感到苦恼。更糟糕的是，有迹象表明她怀孕了。有一天，因谋杀罪而被列入通缉名单的远山抵达里约之前。他拿着一把菜刀，命令她带他去横滨，他女儿住在那里。 10年前，他抛弃了她。里约一开始很害怕，但在得知远山死于癌症后，她试图帮助他见到他的女儿。

Rio is driving her loving dump truck as usual, distressed by the fact that her partner Osamu is into gambling, never paying for anything. What is worse, there is a sign that she is pregnant. One day, Toyama, who is on the wanted list on charge of murder, arrives before Rio. Holding a kitchen knife, he orders her to take him to Yokohama, where his daughter lives. He abandoned her 10 years ago. Rio was freaking out at first, but having told that Toyama is dying of cancer, she tries to help him to meet his daughter.
