Summary
The Titans and the Justice League work alongside the supernatural superheroes Swamp Thing and Etrigan the Demon to stop Circe and Scarecrow, who are planning to enslave humans by turning them into hideous monsters based on their Halloween costumes and cause them to hallucinate of their worst nightmares.

Plot
It all starts with the Titans and Batman pursuing the Joker in the streets of Jump City in his armored truck. Though he manages to slow the young heroes down with numerous traps he leaves in the streets, the Joker is intercepted by Terra (whom he demonstrates himself seriously afraid of due to the last time she fought him), who disables his truck and greatly cripples him like she did last time. The Titans latter decide to enjoy their victory over the Joker in the streets, where people are going Trick of Treating in Halloween, wile Batman goes on to take the Joker to Arkham Asylum. Meanwhile, an unknown force watches from the shadows with a wicked laugh.

The Titans enjoy a night in a Halloween-themed amusement park, where they met with Lois and her daughter Lara. Just then, some of the costumed park employees are suddenly turned into monstrous versions of their costumes and begins to wreak havoc. Right after the Titans (quickly joined in the fight by Batman, Wonder Woman, Geo-Force, Supergirl and supernatural fellow Leaguer Swamp Thing) defeat them, Raven reads the employees' minds but only to find them experiencing their worst nightmares. Wonder Woman deduces that the cause of this is magic, to which the group ends up running to chronicler Jason Blood for answers. Just then, they are attacked in Blood's home by Goblins until Blood summons his avatar, the fiery demon Etrigan.

Right after the Goblins are defeated, Etrigan is able to sense the source of the magic responsible for the chaos in the city and reveals it is both magic from Olympus and scientific experiments which "feeds on Fear". Wonder Woman and Batman eventually deduce that their foes Circe and Scarecrow are behind this and Raven confirms this to be correct when she reads one of the Goblins' minds. She also discovers that Circe and Scarecrow are determined to destroy the "soulless monster who can stop them". Swamp Thing deduces that the "soulless monster" is Solomon Grundy, a hulking zombie who has disassociated from humanity since he lost his soul. While the others go and work to stop the villains, Raven and Swamp Thing search for Grundy, who is initially hostile with both of them until Raven shows Grundy a vision of Circe with a star, which Grundy sees as his lost soul.

Back in Jump City, while the other heroes work to stop the monsters from terrorizing the neighborhood, Batman, Wonder Woman, Nightwing and Terra battle Circe and Scarecrow. Just as the two villains gain the upper hand, Grundy emerges and attack them both, angrily demanding them to give his soul back. Batman manages to strip Circe off her scepter and Wonder Woman breaks it in two and Nightwing and Terra unmask Scarecrow, exposing him and Circe to his Fear Gas. Etrigan manages to drag the fear-infected Circe to his fiery realm where she will face punishment and Scarecrow is taken back to Arkham. Grundy regains and reabsorbs his lost soul and thanks the heroes for his help before leaving back to his swamp. The Titans continue enjoying the Halloween party with Lois and Lara.
