We’ve been talking about Avengers: Endgame plot leaks for months now, as several people out there kept claiming they saw either portions of the upcoming Avengers sequel or the entire thing. While some of these leaks shared some common elements, no two leaks were perfectly similar, making it extremely difficult to attempt to verify any of them. That said, It. Finally. Happened. The monster Endgame leak we never really expected to see, given how fanatic Marvel and Disney are about avoiding MCU spoilers, is here.

Should you choose to go forward with this post note that you’re about to read everything about what I just saw, and I do mean that massive spoilers lie ahead. There’s no way to unsee — well, unread — what you’re about to discover.

I absolutely meant it when I said that huge Endgame secrets are coming. While it’s my business to hunt down these leaks, fully expecting to have my final Endgame experience ruined, I don’t consider that the leak has actually ruined the movie for me. It just makes me want to watch it even more than I already did. This is your last chance to avoid spoilers; here’s a look at an Avengers 4 poster to keep you from reading details about the scenes in the leaked clip.

Before we begin, I’ll tell you that I won’t post versions of the video clip or links to it anywhere in the post. Nor will I share any images from it — most of it is pretty blurry anyway. The ones that follow are from existing MCU films and Endgame trailers. So if you know your way around the internet, you have a bunch of resources at your disposal, including YouTube and Reddit to find the leak and watch it in full.

That said, I’ll tell you the leak contains various scenes that were not shown in any of the trailers, TV spots or any other official clip that Marvel shared with the world. The scenes were shown in a country where Arabic subtitles are needed and recorded on a phone in portrait mode.

However, the leak does confirm several elements of the film’s plot, including details that were mentioned by some of the people who claimed they saw parts of Endgame in the recent past.

The leak tells us how the surviving Avengers will fight Thanos, how they’ll pair up, and where they’ll go. We’re treated to a few epic fight scenes that will give you goosebumps every time you watch it as well as satisfying moments that you’ve been dying to see in Avengers.

If you do chase the clip on YouTube, I’m sure you’ll watch it a bunch of time trying to discover other Endgame secrets. But it will not ruin the entire movie for you. These are just five minutes of more than three hours of Avengers 4 action.

What is definitely interesting about this leak is that it doesn’t really give away the ending. We don’t get to see any hero deaths. It plays just like an extended video clip meant to tease the film. Would Marvel actually risk leaking this kind of footage on purpose with 10 days to go until the premiere? Maybe they would.

UPDATE: A previous version of this article contained a detailed scene-by-scene recap of the leak, but we’ve decided to remove it so that fans of the series aren’t mistakenly exposed to any Endgame content.
