Tommy Lee Wallace
Dr. Daniel Challis and Ellie Grimbridge stumble onto a gruesome murder scheme when Ellie’s novelty-salesman father, Harry, is killed while in possession of a strange mask made by the Silver Shamrock mask company. The company’s owner, Conal Cochran, wants to return Halloween to its darker roots using his masks — and his unspeakable scheme would unleash death and destruction across the country.
A series of murders prompts Mike Hanlon to suspect that the supernatural menace that he and a group of friends battled as children has returned. He begins to call his friends to remind them of the oath they swore: if It returned again, they would come back to Derry to do battle again.
