Adrian, a young guy, is abruptly pulled from his regular existence and placed in an exceptional role in the parallel Earth, wherein cosmic influences determine fates. He has now become Lucifer, the fallen angel, and has been given the job of evaluating humanity's character and suitability for paradise after being chosen by the mysterious higher beings. His mission: to tempt individuals away from the righteous path and thereby assess their true nature.

Adrian emerges on a parallel Earth, brimming with divine power, but he also carries the weight of his appointed task. Both Lucifer and a part of his ordinary self, remain in him. As he battles with this paradox, he comes across souls at a crossroads—people who are dealing with their own troubles, bad luck, or moral quandaries. Adrian must choose whether to follow the heavenly command to seduce them into sin or to step in and guide them towards redemption.

Adrian encounters individuals from all walks of life and sees all the beauty and the sorrow that are part of the existence of humans. With each encounter, Adrian is forced to wrestle with the nuances of morality, empathy, and the range of morally acceptable behaviour.

Will Adrian continue to be the devil, the personification of pure evil, or will he transform for the sake of both the world and him?
