In this wild and woolly universe there’s only three things you can count on. Your brains… your bros…and your bikes! Three of the baddest Mamajammers ever to ride, the BIKER MICE FROM MARS are back on earth and ready to rumble. Let's "Rock n' Ride"! On a mission to save their home from extinction, the Biker Mice have arrived on our planet searching for the Great General Stoker - the legendary Martian leader and the only Mouse with the formula to solve the dire water shortage on Mars. Along the way, our heroes battle those also intent on getting their hands - or paws - on Stoker, including the Catatonians, the craziest Cats ever to have their own planet.
