With the rebel forces closing in, President Snow (Donald Sutherland) orders all civilians to take shelter beyond the capitol walls. Katniss (Jennifer Lawrence) and Gale (Liam Hemsworth) disguise themselves as refugees. Gale is captured and taken away. As Katniss reaches the Capitol gates, a government plane flies over and drops parachutes with small globes on the crowd. The refugees believe they are gifts from President Snow. The globes actually explode killing many of the refugees including Prim (Willow Shields), who is acting as a medic, and injuring Katniss.
But the bombs were actually dropped on the orders of Coin (Julianne Moore) who filmed the massacre to make it look like Snow committed an atrocity against his own people. With the morale of the government troops broken, the rebels win and Coin becomes "interim" president of indefinite duration.
Katniss confronts an imprisoned Snow who informs her of Coin's plot to seize total power. Coin proposes to have one more Hunger Games with the Capitol's children in order to satisfy the bloodlust of the rebels. In exchange for the deciding vote of the interim governing council to proceed with the Games, Coin agrees to let Katniss execute Snow.
At the execution ceremony, Katniss kills Coin with an arrow while the mob descends on Snow. Katniss is imprisoned, but pardoned as Paylor (Patina Miller) is elected the new President of the united districts. Katniss's relationship with Gale ends when she suspects Coin used one of his ideas to eradicate the refugees at the mansion gates.
Katniss returns to the ruined District 13. Peeta (Josh Hutcherson), now fully recovered from the brainwashing inflicted upon him, also returns. Peeta and Katniss fall in love, have two children and though Katniss confesses to her newborn baby that she still suffers from nightmares of the rebellion, it is implied that they will live happily ever after.
