Wan Niang is a demoness who has been hidden in human form for three centuries. She runs an incense store and has one goal in her existence: She wants to gather six scents that – combined – can bestow their owner with remarkable powers. She has already gathered several of these scents, but one – the most important scent of all – is proving very tricky to obtain. That scent is wrapped up in the being of a man named Fang Mo.
