When an obscure figure from the past shows up in his life again, he begins to unravel what happened the day of his sisters disappearance. As the sun goes down on Halloween the showdown begins at Jim's paranoid maniacal funhouse. That night was the longest night of Jim's life and perhaps unexpectedly the last.
