Set a week after the death of YED aka Azazel. Sam, Dean and Gabriel are back on the road; hunting evil and killing monsters. They have their work cut out for them with the release of all the demons from the hell-gate. Along the way, Sam and Gabriel are adjusting to their new relationship and Dean knows that there’s something Sam’s not telling him. Enter the seven sins, walking earth for the first time in centuries. Just when the Winchesters thought things couldn’t get more complicated.
