Later she learns that she was acquitted during her trial, and she's sent back to the ruined District 12, along with Haymitch and later Peeta. Weeks later, Katniss goes back into the woods and is shocked to meet two women. Katniss returns home from the woods one day to find President Snow waiting for her. Gale decides to go with her; Katniss uncuffs Peeta. To her horror, she realizes that this girl is Primrose, her own sister. Cressida and Messalla reappear where they assist the group and order them to escape up the ladder.
Suzanne Collins drew from the myth of Theseus and the Minotaur when coming up with the idea of tributes for the Hunger Games. Back in 13, Katniss and Finnick watch another interview with Peeta, but this time she can see that he has been tortured and is hurt. Katniss is overjoyed to see Peeta, but his first reaction to her presence is an attempt to strangle her. Being unable to control her, President Coin has integrated Katniss into Squad 451, whose job it is to shoot propaganda videos while locating and destroying the pods. Because the revolution has a secret weapon. It has its own missile defense systems against aircraft raiders and has its own life support systems.
Together they destroy the arena and escape the Games. Katniss wants to go to the Capitol and fight, but Coin, saying she's in no shape to fight and too valuable to lose, orders her to stay and shoot more propaganda films. Katniss sees Prim, now a combat medic, trying to tend to the children. The parachutes contain bombs, which blow up a huge chunk of the city. The synopsis below may give away important plot points.
Meanwhile, Finnick and Annie get married. While Katniss tries to sleep, Gale and Peeta reconcile. Peeta, Annie, and Beetee are strongly against the idea, but Johanna and two other victors are in favor. Suddenly, Katniss realizes that Coin wants her dead. Plutarch offers no objections, so Katniss agrees. His warning gave the rebels time to hide underground, and no lives were lost. The night before the mission is scheduled to leave, Katniss overhears Peeta and Gale talking about her.
She is enraged at this disregard for human life and an attack on the defenseless and weak. But Boggs is one of the first casualties. He explains the Capitol started dropping bombs after the Games. Gale tells Katniss that this is war. Lionsgate Entertainment acquired worldwide distribution rights to the film adaptations of The Hunger Games, which is produced by Nina Jacobson's Color Force production company.
After a month, Katniss succeeds in qualifying for the mission. The next mission is to the Capitol itself, but Katniss is not invited to join it, since she needs more time to recover. During the battle that follows, Katniss gets shot. In District 8, Katniss and Gale visit a makeshift hospital and meet. Government soldiers, recognizing Katniss and her friends, shoot at them, and in the chaos Katniss is separated from the mission. A dense fog descends on them and turns out to be a toxic nerve agent.
Over time, Katniss is able to grieve for her sister and the many others who died. After demanding that she be allowed to execute Snow, which Coin agrees to, Katniss says 'yes' for Prim, although she becomes aware of Coin's motive. Her father taught Suzanne and her siblings about war at a very young age, and Collins believes that children should be aware of the ethical ambiguities and ramifications of conflict so that they can participate in a beneficial dialogue with their parents and other adults. Citizens of District 13 retreat underground for several days. Gale is captured by the Peacekeepers and dragged away. The remaining group fights them off and tries to escape. Katniss, Gale, and many of the former residents of District 12 now live in District 13, which is located almost entirely below the ground.
The mutts chase the rebels through the tunnels, with Jackson bravely staying back to defend her fellow soldiers. In part because of Katniss's vote, the answer is yes — the Hunger Games will start again. The programming inflicted on Peeta in the Capitol eventually makes him freak out. The rebels agree to this plan, and the next day, a bomb goes off in the Nut, causing many innocent people to die. She delivers a fiery message to Snow, all of it captured by her fearless camera crew. Katniss fires an arrow toward it, which triggers a giant explosion. The revolution begins in spurts when strikers in District 7 kill an entire team of Peacekeepers soldiers from the Capitol in the forest with hidden land mines and a rebel demolition team destroys a huge dam that provides the Capitol forces with electricity for their city.
Beetee, a rebel agent who competed in the Hunger Games alongside Katniss, has designed explosive arrows for her. Once in District Two, Commander Paylor mentions that the Rebellion failed to capture the arsenal from the Nut, a huge mountain containing Capitol infantry. Nevertheless, she will be exiled for some time to her old District Twelve. Now, they will work together to win this war and rescue Peeta. In the epilogue, Katniss shares that she ended up with Peeta because she needed his faith and loyalty more than Gale's inner fire since she has enough of her own.
