I think it'd pretty much have to be a script, a screenshot, audio, or video to qualify as copyright infringement. I can tell you what a song is about without risk of violating copyright, but the moment I start quoting lyrics things get riskier.
I think it depends on the depth of the summary, and the purpose. You can do quite an indepth analysis as part of educational material for example, which is one of the tests of fair use.
I think a key thing to remember when assessing your own liability is fair use is a defense, not an automatic guaranteed right for blanket uses.
Leaking spoilers of unpublished works can definitely cause market harm, and serves no wider good for the market the same way educational material would.
I wouldn't like to be on the receiving side of this lawsuit. At the very least it's going to be expensive to defend against.
