Dean is an FBI agent from the SPN unit, who professionally hunt all over the USA with encouragement from the government. Everyone knows that angels exist, and while he had never laid eyes on one himself, Dean grudgingly acknowledges their existence. Until overnight, his world is turned upside down when a garrison of angels descend on the FBI headquarters in Phoenix, Arizona. Partnered with the arrogant and socially oblivious angel Castiel, Dean must get past his ingrained fear of the supernatural, and the painful memories that Castiel pulls to the surface. But when the angels appear to have a secret agenda, Dean's budding relationship with Castiel is put to the test, and the two of them have to choose what's most important to them — family, or duty.
