Hosted by William Shatner, each episode of Weird or What? contains three separate stories of the bizarre and unexplained. As the show unfolds, it weighs various supernatural and scientific theories that attempt to explain the story, and sometimes features tests conducted as proof of a theory's plausibility. The show features strange occurrences such as aliens, ghosts, monsters and natural disasters, and could lead you to question your understanding of what is real, what isn't, and what's just plain weird.
