Sam and Dean are directed to a small town where the people are prepared to kill demons and a young woman declares herself a prophet.
Next on "Supernatural" the Winchester brothers are plagued with "99 Problems". Sam and Dean are outnumbered by demons, but are saved at the last minute by Rob and his townspeople, who are aware of the Apocalypse, and have been training to fight and kill demons.
The small town is very religious and Sam and Dean meet Pastor Gideon, who introduces them to his daughter Leah, whom he claims is a prophet. Leah tells the townspeople they must obey her orders if they want a spot in Heaven but when she starts turning the townspeople against each other in the name of the Lord, the brothers realize they must kill her.
"99 Problems" airs on April 8. Michael Shanks from "Stargate Universe" guest stars as Rob, Larry Poindexter from "State of the Union" as Pastor Gideon and Kayla Mae Maloney from "CSI: Crime Scene Investigation" as Leah.
