Father Adam Day was the youngest brother of a three-brother criminal team called the Day Crew during the Thatcher era. After his older brothers were killed in a police shootout, Adam became a priest and worked to reshape his image.
In the modern day, after discovering that Margaret Ames had become vulnerable to magic due to her association with John Constantine, Father Day orchestrated a plan to bring his brothers back to life, using a spell to bring his brother Burke back in Ames' body. However, this spell would accidentally cause Ames to become a bridge to Hell, which the demons planned to use to takeover the world.
