Dean and Sam a saved on the road from a demon attack by a group of citizens from Blue Earth, a small town in Minnesota. They discover that the pastor's daughter Leah Gideon has visions with the angels and tells them where the demons are. Their followers believe that the will live in Paradise on Earth after the Apocalypse. Sam calls Castiel and when he arrives, they discover the truth about Leah.
"99 Problems" is a good episode of Supernatural, with action, funny moments and dramatic conclusion. Let's see the option chosen by Dean in the next show. My vote is eight.
Title (Brazil): "99 Problemas" ("99 Problems")
