Tomorrow night, Syfy premieres the new series Weird or What? with host William Shatner.

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.

Weird or What? premieres on Tuesday, April 30 at 9/8c.

Here are two promo clips and Syfy has a preview gallery of the first season’s 10 episodes.
