Movie remake of the Yoshiwara Enjou arc.
 

Upon meeting a young boy named Haruta who makes a living as a pickpocket, Gintoki discovers that he is pickpocketing out of a desire to meet his long-lost mother, Hiwa, Yoshiwara's number one courtesan. Gintoki and his friends venture to Yoshiwara to fulfill Haruta's wish, but standing in their way is Housen, the Night King who rules Yoshiwara.

The samurai didn't stand a chance. First, the aliens invaded Japan. Next, they took all the jobs. And then they confiscated everyone's swords. So what does a hotheaded former samurai like Sakata "Gin" Gintoki do to make ends meet? Take any odd job that comes his way, even if it means losing his dignity.

Life isn't easy in feudal Japan... especially since the aliens landed and conquered everything! Oh sure, the new health care is great, but the public ban on the use of swords has left a lot of defeated samurai with a difficult decision to make concerning their future career paths! This is especially true if, as in the case of Gintoki Sakata, they're not particularly inclined towards holding a day job, which is why Gintoki's opted for the freelance route, taking any job that's offered to him as long as the financial remuneration sounds right. Unfortunately, in a brave new world filled with stray bug-eyed monsters, upwardly mobile Yakuza and overly ambitious E.T. entrepreneurs, those jobs usually don't pay as well as they should for the pain, suffering and indignities endured!
