In the year 2033, after a decade-long global drought in the wake of a comet striking the Earth, the little remaining water is controlled by Kesslee (Malcolm McDowell) and his Water & Power (W&P) corporation, which subdues the population by monopolising the water supply. Rebecca Buck – "Tank Girl" (Lori Petty) – is a member of a commune in the Australian outback that operates the last water well not controlled by the corporation. In an attack on the commune, W&P troops kill Tank Girl's boyfriend, Richard (Brian Wimmer), and capture Tank Girl and her young friend Sam (Stacy Linn Ramsower). Rather than killing her, Kesslee enslaves and tortures the defiant Tank Girl. Jet Girl (Naomi Watts), a talented but introverted jet mechanic who has given up trying to escape W&P, urges Tank Girl to make less trouble for their captors, though Tank Girl refuses. Among other forms of torture, W&P personnel push her down into a long pipe to induce claustrophobia.
