A very short, low quality version of the first movie. Go watch that if you're interested in what happened.
Okay, okay, so they added elements of TLG into the video, such as Scar being in charge of his Lion Guard, and adding Kiara and Kion to the end.
However, something that kinda peeved me off: It's understandable to have Simba remember Mufasa as a great ruler who did no wrong, due to him being Mufasa's son, and only knowing him for a relatively short time. But to hear Rafiki describe Mufasa in the video in a way that also seemed near worship-like, it got me thinking: shouldn't Rafiki know better?
