Gintoki Sakata is a lazy samurai living in an alien-ridden Japan where samurai are no longer needed. This OVA is a set of short comedy stories involving Gintoki and his equally-broke sidekicks Shinpachi and Kagura. One day, Gintoki and his comrades are out viewing the spring flowers when suddenly the Shinsengumi appear, arguing that Gintoki has taken their flower-viewing spot. Gintoki's team and the Shinsengumi must then battle for the right to sit in that spot by using a violent version of rock paper scissors.

This episode shows various scenes from the war between samurais and the Amanto, focusing on Gintoki's fights alongside Kotaro Katsura, Shinsuke Takasugi and others. In the end, the episode is revealed to be a trailer from a film, which was in fact fake.
