Due to the COVID-19 pandemic, Supernatural was not produced in 2020 and has one fewer season than True Crime because production was unable to secure haunted locations to visit under quarantine.

[citation needed] In the show's Supernatural seasons, Madej and Bergara travel to places with haunted folklore in order to attempt to find evidence of paranormal phenomena.
