Katniss, Peter and Haymitch train before the reaping so they are at their physical peak as they know Katniss will be picked and Peter or Hayitch.
The reaping where they find out that either Peter or Haymitch will be in the arena with Katniss. Haymitch is chosen but Peter volunteers again.
In the capitol
Katniss and Peeta are taken to the capitol after being chosen for the 75th Hunger Games. While they are there they train again learning more vital information to survive in the arena.
In the arena
After being in the capitol the tributes are taken to the mystery arena again but this time it is sea based cornucopia and Katniss is in a team with Peeta, Finnick, Johanna, Wiress and Beetee.
Katniss survives the bloodbath (the starting of the games where the most kills are) by being saved by her team-mate Finnick and most of her team meet then but later comes Johanna with Beetee and Wiress.
Johanna brings Beetee and Wiress.
When Johanna arives with Wiress and Beetee, Wiress wont stop singing songs about clocks so Katniss gets the idea from that that the arena is a big clock and every hour something happens e.g. Lightning strikes a tree or a tsuinami will go from the outside to the center of the arena.
Explodes the barrer and gets taken away.
Katniss' team work together using a metal rod that when the lightning strikes a tree the voltage will go down the rod and into the barrer and will explode it. This successfully works and Johanna cuts out Katniss' tracking device aswell so that she cant be tracked and is taken away to district thirteen.
Finds out what really happened.
Katniss is told that district 12 was blown up and really district 13 is still there and people live there underground as the people who originally lived there where mining underground and where lucky to live.
