My podcast “Highway to Heaven Revisited” might be what you are looking for, we do a beat by beat recap of each episode. The premise is my wife and I watch the episode and then retell it to our friend Sam, a professional actor and filmmaker, who doesn’t watch the episodes. https://highwaytoheavenrevisited.com

Also I’d recommend “The Twilight Pwn” they also do a thorough beat by beat retelling of Twilight Zone episodes. $1

I dont have any places that would give you the plot lines of a movie, but if you are wanting to watch movies, find some that have digital video service on the back of them.

That provides verbal explanation throughout the whole movie.
