The series itself is in the jidaigeki genre (Japanese for an Edo period drama). The cast of both movies feature actors from the Super Sentai Series' recent programs, primarily from Tokusou Sentai Dekaranger and Mahou Sentai Magiranger.

Jun Terada is a producer in the year 2076 and is trying to convince the president of Magical TV to allow her to create her life's work, Cho Ninja Tai Inazuma!, based on the long-standing legend of a legendary lightning that bestows powers upon those struck by it. However, because the show is to be the 100th anniversary of the , it must be a first for the 100-year-long franchise. President Mishima convinces her to turn it into a reality show by traveling back to 1720 in the Edo period and picking three extremely inept locals and force them through humiliating training to become ninja.

When Jun and her writing partner Kuratanomiya arrive in the past, they find Hosomatsu, Kankichi, and Kaguya, three extremely cowardly, inept, and clumsy individuals, to be the stars of their show. Jun, as a Kami, begins to train the three, fooling them with futuristic technology and giving them self-confidence. Unbeknownst to Jun and Kuratanomiya, there are actual monsters killing various people throughout O-Edo, while Jun trains her Inazuma team. When Kuratanomiya encounters the villains on a night on the town, who turn out to be the trio's idols possessed by evil slug-like monsters, Jun must reveal the truth to her stars that they are without power, but the trio decide to fight anyway with Jun's earlier words taken to heart. But learning that the legendary lightning exists, Jun discovers that it's the spark from the glitches in the time teleport system that created the monster slugs. With that knowledge, Jun sends Kuratanomiya back to the future so she can become an antenna for the legendary lightning and empower the Inazuma team before they are killed by the three monsters.
