In "Insidious: Chapter 3: From the Ghost", Lin Shay returns to play a supernatural psychologist. Directed by Adam Roberti, the director of "Amnesia", and written by Leigh Whannell, one of the original team of the "Insidious" series, and produced by the genius director James Wan, the film will create the latest classic of extreme horror. "Insidious: Chapter 4: The Dead Key" will not only bring a new story with double the horror, but also a more comprehensive upgrade in production scale than before. The director said in an interview: "Before filming, I even sent special effects artists to a 200-year-old abandoned prison in Philadelphia, USA for inspection. I believe that only by experiencing the oppressive darkness and extremely unbearable atmosphere can we truly present the most horrifying scene of imprisonment." The story tells that the psychic Alice accidentally brought him back to the past that he was most reluctant to face during an accidental case investigation, and was forced to face the most feared secret in his heart, "Fear is the only way to go home..." She will be forced to "go home" to face the most feared dark shadow in her heart. Lin Shae, who plays the psychic in the Insidious series, is undoubtedly the soul character throughout the movie. The new work Insidious: Chapter 4: The Last Key will reveal more about her background. Lin Shae said: "This story will explain many of everyone's questions, such as why Alice can become a character who communicates with the spirit world, and more of the suffering and unwillingness she endured under this "gift". I believe that fans will be able to empathize and resonate more deeply with this character."
