Luckily, the site was able to show a preview of around 10 minutes. That was enough to find myself! I paused and I took a picture haha.
The talent and the production crew were awesome. They were super cool and chill. It was a great day haha. I hope I can find the full episode soon.
It was about a Rembrandt painting. I think the specific episode is called: 'Strange Inheritance': Family who suffered at the hand of Nat Turner OR Rembrandt found in an NJ basement.
