Basing on the time setting of this episode, it would mean that Halloween episodes of Walker seem to always take a horror turn. Of course I can definitely say that it definitely seems like a perfect excuse. There are only two Halloween-based episodes of Walker: This one and "The Children of Halloween", and both episodes are rather trippy and I mean TRIPPY.
The episode goes like this: There had been some deaths occurring and no evidence had been shown what the causes were. At the beginning of the episode, two teenage boys go to some construction site which happened to be at an Indian burial ground. Suddenly, the boys encounter some mysterious Native American who sort of clones himself and unleashes the spirits of the dead to kill those who disturb the spirits. Someone witnessed the murder happening. There was also an attempted murder with someone. Some didn't believe anyone's story about ghosts hunting down people under the guide of the medicine man named Running Wolf. So Walker goes to the Indian reservation to talk to his mentor White Eagle about dealing with the spirits and Running Wolf. However, it wasn't easy. The whole episode I thought was a trip. It was cool how it delved into the supernatural a little bit, but it was kind of creepy if you think about it. I bought the third season DVD today. I know it's usually shown on USA, but I had never seen it. However, I do notice that it's never shown on Hallmark and I can definitely see why. It wasn't a bad episode, but it was one that if I watched it back when it aired, I would've been creeped out completely, especially how young I was then.
