It's the grand finale of "Harley vs. Apokolips"! Harley's trapped on Darkseid's homeworld, having failed to become a Female Fury under Granny Goodness' tutelage. Trapped in a "reeducation chamber" that threatens to destroy her free will, Harley must dig deep to throw off the alien shackles and get back to Earth. She just needs to escape a super-max alien prison, fight off a planet full of super-powered psychos, defeat a New God, then steal a spaceship and fly it home. No problem-o!
