Through the ordinary small events of his professional and personal life, a forty-year-old man lets himself go on impromptu escapades at random along the paths that the big city offers. This vagrant impulse soon takes on the appearance of a sentimental journey, punctuated by images of the walker's youth.

In Europe, in France, in Paris in particular, the lives of three people intertwine as business and other affairs unfold. Yoshiaki Hongo is the polyglot son of a well-traveled Japanese banker, who now works as a "trader," or "smuggler." Narcissistic, he likes to work out and sculpt his body, to make up for his lack of stamina in bed. Rintaro Norimizu is a former member of the Japanese SDF and French Foreign Legion who fought in Chad and Libya. Now he is a mercenary who sells his services to the highest bidder. Fuchi is a Vietnamese woman of Chinese descent, a fashion model who fled Saigon by helicopter at the age of five, who likes to use her charms to get what she wants. Through four independent story-lines, we follow the misadventures of these characters, sometimes opposed and sometimes joining forces. (Source: Pika, translated)
