The heavy-weapon honey with a mouth like an open sewer has returned! So, here's what's happened: Booga, Tank Girl's marsupial lover, is near death.

But their Incredible Expedition goes horribly wrong when, deep in Booga's scrotum, Tank Girl encounters her ultimate opposite: Anti-Tank Girl! There may be trouble ahead!
