The CW have released the official poster for the ninth season of "Supernatural" which returns on October 8th. The poster refers directly to the last few minutes of the eighth season finale which saw angels falling from heaven. A new synopsis has also been released:
"Dean is frantic after Sam collapses and the doctor tells Dean his brother won't make it. Desperate, Dean sends out an all points bulletin via prayer to every angel in the area, asking them to help his brother. In exchange, Dean will owe that angel a favor.
Numerous angry angels race to find and kill Dean, but one, Ezekiel, gets to him first. Meanwhile, Sam fights for his life and must face some familiar demons to do so. Castiel struggles to survive without powers."
