There is always more to the world than meets the eye. This is the motto that twin brothers Sun Xiaotu and Sun Xiaohu follow in their lives as paranormal investigators, where what may be terrifying to some is just another day at work. Normally, it is simple for them to separate their daily lives from their job, but when they go to investigate a seemingly typical haunting of a pair of twins, a series of bizarre events throw their perception of the supernatural world into question as they become a target of the hauntings themselves.
The further the brothers search for answers to the paranormal mysteries thrown at them, the hazier the lines between truth and fiction become. Through the challenging and sometimes dangerous adventures ahead, one question remains: what kind of secrets are the ghosts trying to hide from them, and are they already more connected to the spirits than they originally thought?
