The series focuses on Lucifer Morningstar, a handsome and powerful angel who was cast out of Heaven for his rebellion. As the Devil, Lucifer tires of the millennia he spent being the Lord of Hell, punishing people.
Becoming increasingly bored and unhappy with his life in Hell, he abdicates his throne in defiance of his father (God) and abandons his kingdom for Los Angeles, where he runs his own nightclub called Lux. When he finds himself involved in a murder investigation, he meets the intriguing Detective Chloe Decker.
