A freak tornado pulls Dorothy Gale into the wicked world of Oz just in time for the down-on-her-luck Kansas farm girl to confront Glinda, a starving cannibal who finds herself all out of Munchkin meat. Things go downhill from there, as Dorothy goes head-to-head (literally) against a skull-cracking Scarecrow, a Tin Man whose hobby is to collect still-beating hearts and a Cowardly Lion who pleases his master by ripping apart anyone he sees. Oz becomes Ooze as Dorothy – armed with scavenged weapons – battles her way through hordes of psychotic enemies until she finally happens upon her ultimate nemesis, the Wicked of Oz.
