In a small and mysterious town in California, a man named Donovan finds his way to Dr. Challis's clinic after his wife is brutally murdered by a masked stranger. As he recuperates, he discovers that his wife had a sinister connection to a famous toy company that is about to launch a line of Halloween masks. Intrigued by the connection, Donovan joins Dr. Challis to investigate further about the company, Silver Shamrock, and its enigmatic founder, Conal Cochran.
As they delve deeper into the plot, the two men uncover that the masks are not mere accessories for Halloween, but conceal a dark secret involving an ancient Celtic rite. Cochran has plans to use the power of modern technology combined with ancient magic to carry out a terrible sacrifice that could end the lives of millions of children on Halloween night. The race against time intensifies as Donovan and Challis try to unravel the truth before midnight on October 31st.
With a chilling atmosphere and a biting critique of the commercialization of festivities, this film deviates from the typical slasher narrative and ventures into the realms of psychological horror and the supernatural. What appears to be a simple Halloween tale transforms into a nightmare that raises unsettling questions about control, tradition, and technology in modern society.
