It's a series of recorded phone interviews.

He lays out the gist of how things came to light in the first 15 minutes.
It's a lot to take in. I listened a bit at a time over a few days. It's very disturbing.

But here's a quick summary of the intro

Sascha claims he was badly beaten by men & also raped & filmed, his adoptive father, a pilot for Epstein trafficked him through Epstein, Sascha was reminded of his abuse when during his military career he was called to attend a meeting with his commanding officer & told they had found child sexual abuse material on another officers computer & one of the videos had a child in a video that they felt looked like Sascha, Sascha confirmed it was probably him as he'd had such things in his past

He goes on to share his story. Trump and a few others are mentioned as abusers. His last encounter with Trump he injured him in retaliation.

I have seen things that have verified some of the details he shared. But like everything there's a lot of opinions around it too.
