In the episode, God assembles a team of angels, demons and witches in an attempt to lock Amara away using the Mark of Cain to be transferred to Sam.
Lucifer (Misha Collins) is mad at God (Rob Benedict) for having punished him as well as having trusted the Mark of Cain in him and refuses to speak to Him.
Meanwhile, Crowley (Mark A. Sheppard) summons a meeting between demons but they refuse to go along with his plans to retake Hell because of his previous incidents.
Rowena (Ruth Connell) arrives with a witch, Clea (Barbara Eve Harris) to carry on a spell.
When that was proven wrong, God was angry at Himself, confessing that was part of the reason He banished Lucifer along with protecting humanity and this causes them to make amends.
Castiel temporarily retains his body and goes back to Heaven to convince the angels to join them, and Dean goes to Crowley for help while Sam interrupts Rowena and Clea to get them on board.
Inside the bunker, Sam and Dean stare in shock at God's body, with Amara stating that she wounded Him and He will slowly die but not before watching the humankind "turn to ashes."
