The Lupinrangers aim to reclaim the stolen Lupin Collection to rescue loved ones. The Patrangers pursue the Gangler thieves to recover the collection and serve justice. Both teams battle each other and the Gangler in their missions.

The Lupin Collection, a vast ensemble of dangerous items acquired by the legendary gentleman thief Arsène Lupin, was stolen by an interdimensional crime syndicate known as Gangler. The Gangler receive opposition from two Super Sentai teams: one being the Lupinrangers who aim to steal back the collection to not only live up their namesake's reputation but also wish back those they have lost. The other team are Patrangers, tasked to uphold justice by retrieving the collection and taking down the members of Gangler. Both teams fight not only the Gangler, but each other, in order to collect the pieces of the Lupin Collection.
