Jake Baker lives in Niagara Falls with his uncle Calvin, a kind but eccentric enthusiast of occult artifacts and conspiracy theories. The summer Jake turns twelve, he befriends a pair of siblings new to town, and initiates them all into the "Saturday Night Ghost Club". But what begins as a seemingly light-hearted project may ultimately uncover more than any of its members had imagined. An irresistible, and bittersweet coming-of-age story in the vein of "Stranger Things" and "Stand by Me".
