Before the return of Supernatural (Thursday, Sept. 18 at 9 pm/ET, the CW), check out where we last saw the Winchester boys and what cool and crazy storyline lie ahead for them this season.

Where we left off: Ruby ( Katie Cassidy) was possessed by the demon Lilith. Then she trapped the Winchester brothers and sent Dean ( Jensen Ackles) to Hell, thus fulfilling Dean's contract to sacrifice his life for Sam ( Jared Padalecki).

What's next: Dean rises from the dead! The season opens four months later with the supernaturally healed elder Winchester brother digging his way out of his own grave. "We kick off the season with the primary mystery - how did he get out, who got him out and why," creator Eric Kripke says. Meanwhile, a grieving Sam is dallying with a pretty waitress ( Wildfire's Genevieve Cortese).

Lucifer rising: Lilith gets busy on a conspiracy aimed at unleashing the biggest baddie of all: the devil himself. "Lucifer has been gone so long that most demons don't believe in him anymore," Kripke says, "but if Lilith's plan works, that's big, big trouble."

Grandfather knows best: Mitch Pileggi ( The X-Files) plays the boys' grandpa in an episode that flashes back to Winchester parents John and Mary's first get-together.

Tricks and treats: A black-and-white episode pays tribute to classic monster movies of the 1930s and '40s, with the brothers fighting off Dracula, the Wolfman and the Mummy. Another episode explores the origins of Halloween. "We're returning to the dark, bloody beginnings of this very frightening pagan holiday," Kripke says. Spooky!
