Host Damaris Phillips teams up 14 of the world's top carvers to compete in an epic battle of creating larger-than-life masterpieces that defy imagination. The carvers pursue their dreams by bringing terrifying nightmares to life: being chased, losing teeth, falling, naked in public, feeling lost, being trapped and bugs on you.  Impressing the panel of elite judges, Imagineer Terri Hardin and world-renowned pumpkin sculptor Deane Arnold, will put the teams one step closer to the title of All-Stars Champion and a whopping $50,000 prize.

Host Damaris Phillips invites veteran judge Terri Hardin and guest judge Dan Langan to the patch in order to bear witness to a crime scene. She tasks each team of all-stars with carving a specific spooky crime location, a peccant perpetrator and a monstrous murder weapon. Fortunately for all, the Special Pumpkins Unit is on the case.

The all-stars competition heats up as host Damaris Phillips invites the remaining carvers into a mad scientist's lab, where they will create two horrifying hybrid beasts battling each other in an epic duel. The artists push their limits as they work to impress resident judge Terri Hardin and guest judge Kim Miles, interior designer extraordinaire, but a last-minute disaster forces one team to scramble with only seconds to go.

Host Damaris Phillips challenges the remaining teams to bring everything they've got to ensure their spot in the all-star grand finale. To move on, the teams create their own supernatural-themed stories, contend with another jarring jump scare and carve their way into the minds of veteran judge Terri Harden and special effects designer Anthony Kosar.

The final all-star teams looking to be named rulers of the pumpkin patch find out not every fairy tale has a happy ending as host Damaris Phillips tasks them with turning a classic children's story into a scary tale. Judges Terri Hardin, Dan Langan and Duff Goldman decide who lives happily ever after, earning one team the title of Outrageous Pumpkins All-Stars Champions, the hallowed prize belts and $50,000.
