Mystery Hour is a fictional queer horror radio drama. Persy and Sammy, two best friends who live in the quiet fictional suburbs of Twin Oaks, think it's time to call it quits on their failing urban legends radio show. But as one last huzzah, the pair decide to prank their listeners on their last show by creating their own monster. While the final show is a hit, they realize the creature they made up has manifested into something real.
