I LOVE the Hunger Games. How are you confused? Did you watch the whole movie?
Have you seen the first one? If not, the second one can be confusing.
If you're confused about the ending of the second one, Katniss ended the game by shooting an arrow connected with wire in the sky when lightning struck. This caused the arena to collapse and the game to end. Peeta got captured but they got Katniss out and she was unconscious. When she woke up, she found out that Peeta was captured and that this was the beginning of the revolution against the government.The creator of the game who initially seemed like he was on the President's side, was actually working for the side of the rebels who began rebelling against the President.
Basically, they had planned the whole game and most of the tributes were in on it. However, they didn't tell Katniss or Peeta because the President was watching them and it was too risky to tell them the plan.
Okay, that's pretty much the basics of what happened (if you are, in fact, talking about the second movie).
a lot of the questions you have are answered in the third book and will be addressed in the movie
but in the last scene you see Finnick, Plutarch, Gale, and Haymitch. we see Beatie is in rocovery on the bed next to Katniss. We are told by plutarch that Peeta and Joanna are alive but being held by the capital. We know katniss' mom and sister were saved before the district was destroyed.
Hopefully that answers the question. I don't want to give away things from the third book. but I would def recommend reading the books as they are infinitely superior to the movies (although the second movie was def better than the first). And I don't typically think people HAVE to read the books that get turned into movies
