This season will find Special Agent Nick Cullen finally realizing his dream of joining the FBI, only to quickly discover being an FBI "special agent" isn't what he expected it to be. When he's assigned to a seemingly dull observation detail, he finds a potential career case in the form of an emerging cult, and when a large scale operation takes aim at the cult, it's unclear which side will break first. Despite the promotion, Cullen's path continues to cross with former partner Judd Tolbeck's, who is also adjusting to life with a new partner of his own.
