Based on the British cult comic-strip, our tank-riding anti-heroine fights a mega-corporation, which controls the world's water supply. Tank Girl (Rebecca) and her friends are the only remaining citizens living in the wasteland that is Earth, where all the remaining water is controlled by Water and Power, the mega corporation/government that runs the territory. While incarcerated at W + P, Tank Girl and her new friend Jet Girl break out and steal... a tank and a jet. After meeting some mutant kangaroo/humans, and rescuing her little girl (adopted by her friends), the kangaroos and the girls kick Water and Powers' butt.
