Your references to Ghosts sounded familiar, so I looked it up. It's a UK TV show made by the BBC, and I now remember watching a couple of episodes when it started in 2019. There have currently been three seasons of the original. By your character references, I'm guessing that you're watching the US remake. The Viking in your version is a caveman in the original, and other characters have apparently been Americanized. Here's a short trailer for the UK version.
