The centuries-old enchantress Circe transforms Wonder Woman into a pig as revenge against Diana's mother. Batman and Zatanna work together to return her to normal, while B'wana Beast attempts to find the "Wonder Pig" before she's butchered at a slaughterhouse. It contains the famous scene of Batman singing the jazz standard "Am I Blue?" to a nightclub audience.

The Justice League battle Mordru in the background, while the narrative follows Booster Gold as he attempts to close a walking black hole while he's supposed to be on "crowd control".
