Between darkness and deliverance.
When they were boys, Sam and Dean Winchester lost their mother to a mysterious and demonic supernatural force. Subsequently, their father raised them to be soldiers. He taught them about the paranormal evil that lives in the dark corners and on the back roads of America ... and he taught them how to kill it. Now, the Winchester brothers crisscross the country in their '67 Chevy Impala, battling every kind of supernatural threat they encounter along the way.

Dean begins to think the only way to stop Lucifer is to say yes to Michael, but the angels decide they don't need him anymore. Dean, Sam, and Castiel are horrified at the angels' new game plan and take on Zachariah to prevent an all out war on Earth. Meanwhile, a familiar face returns.
