After witnessing the destruction of his home, Hazardian Dapp must find (and somehow convince) five humans of the Pegasus Garage who possess the connection with legendary car constellations to become the Carranger and save their planet from the destructive force of the evil planet-destroying Bowzock.

The Carranger escape from Dappu's explanation of their new Giga Formula weapon only to need it to take on a Gorotsuki who wants to use car noises as a signal to get the Earth blown up by other aliens.
