You might be able to watch it on some documentary channels like National Geographic or Discovery. They often feature shows that delve into the inside story of various events or topics.
The Inside Story could be accessible on certain subscription-based streaming services. You could also look on free streaming sites, but be cautious as the quality and legality might be questionable.
You could also check your local cable TV channels or search for it on dedicated movie and TV show websites. Just make sure they are legal and reliable sources.
I'm not sure where you can watch it as the title is a bit unclear. It might be available on the TNT official website if it's a TNT - produced show. Or it could be on some streaming platforms that have TNT content.
There's no way to accurately tell where one can watch 'watch tnt inside story' without more information. If it's a promotional or exclusive content piece, it might be only accessible through certain TNT subscriptions or memberships. It could also potentially be on a new media platform that TNT is using to showcase their behind - the - scenes content, but again, this is all guesswork.
