If you don’t have the time to watch all 21 movies in the Marvel Cinematic Universe before you see Avengers: Endgame this weekend, a massive MCU recap, courtesy of Screen Junkies, can get you up to speed in less than 40 minutes. (Not bad compared to a 59-hour movie marathon.)

The video explains everything in the MCU, but in a different way than most other recaps: Rather than recounting the details of each movie, it breaks the entire Marvel universe down by character and gives a timeline of how and when each Avenger made their way into the series.

The 38-minute video kicks off with Captain America, as he was the first Avenger (going all the way back to the 1940s). It then explains how the stories of the six key Avengers—Iron Man, Captain America, Thor, Hulk, Black Widow, and Hawkeye—cross.

The video finishes with the events of Avengers: Infinity War, where half the world’s population, including many of our favorite superheroes, was turned to dust at the hands of Thanos.

While going through each character, Screen Junkies give us exactly the facts we need to know without leaving anything out. Whether you're a complete novice to the series or simply looking for a refresher course, it's the best way to get you ready for Avengers: Endgame.
