The Boonboomgers' run in the Big Bang Grand Prix is violently interrupted when the universe's top-ranked monster, Universe No. 1, appears and triggers a catastrophic universe fusion, causing parallel worlds to merge into one chaotic continuum. While Taiya Hando/Bun Red is suddenly transported to Planet Shaft, he's attacked by the Bitter Demon Beast Galaxy Circuit Guruma until Hoeru Tono/Gozyu Wolf arrives to back him up. Meanwhile on Earth, the remaining Gozyugers battle Universe No. 1. Bun Blue, Bun Pink, and Bun Black return to help, but the monster overwhelms them and defeats the combined teams. Hoeru then reappears in a dramatic new evolution: Saint Gozyu Wolf, declaring his vow to "stop the battle." With a slash that cuts through space itself, he sends all eight heroes hurtling into another dimension, setting the stage for the film's multiversal conflict.

Celebrating the 20th anniversary of the Tokusou Sentai Dekaranger series, the six detectives who fight with cool and burning hearts gather again to face the "Great Plan" that threatens peace on Earth!

Eight years after saving the SPD from Agent Abrella's scheme, the Dekarangers parted ways with Ban joining the Fire Squad, Jasmine marrying Hikaru Hiwatari, and Swan working independently while Tetsu, Hoji, Sen, and Umeko continue working under Doggie Kruger. But after an incident occurred that hospitalized Kruger on planet Revaful wherein he was labeled as a dirty cop for an apparent dealing with the Qurlian Crime Family, which went awry with the death of a civilian witness, Tetsu takes over the Earth Branch. Two years later, joined by rookie officers Assam Asimov and Mugi Grafton, who had taken over the positions of Deka Red and Deka Yellow respectively, Hoji, Sen and Umeko encounter a Clementian named Carrie who is being hunted by Mechanoids.
