Odd Jobs Gin has taken on a lot of odd work in the past, and when you're a Jack of All Trades agency based in a feudal Japan that's been conquered and colonized by aliens, the term "Odd Jobs" means REALLY ODD jobs. But when some more than slightly suspicious secrets from the shadows of Gintoki Sakata's somewhat shady former samurai past and a new pair of odd jobs collide, the action is bound to get so wild and demented that only a feature film will do it justice!

Scientists and police are on the hunt for half-human/half-beast creatures and between that, of course, is sex. Linda, a member of the SWAT team, was pursuing Kata, who was suspected of being infected with a virus. A man named Mustang, a person from the same tribe as Kata, was waiting for her when she went to Kata's apartment. He told Linda, "A bad dream is blowing through this city." In another part of the city, Kata, having braved the virus, was assaulting and having sexual relations with men left and right and spreading the contagion. The city was overrun by infected men that had transformed into beastmen, and marching orders were given to Linda and the others to manage the state of emergency. What can be done to settle this situation...?
