I didn't get it. I think it's trying to depict social anxiety, using some codes of the horror movie.
We follow this guy, Pete, played by Tom Stourton. He meets a bunch of old friends in a mansion, and he hasn't seen them for a few years it seems. And then the entire movie is depicting situations where Pete's friends are awful to him. Not really straight up mean, but kind of shitty and then either gaslighting him or saying that was just a joke.
And... that's it. It's unclear if he has really terrible friends, or if he's paranoid and things are in his head. But either way, I don't really see the point.
At least, it's well paced and relatevely short.
