The Hunger Games: Mockingjay, Part 1

Katniss Everdeen reluctantly adjusts to a highly structured life in the underground District 13, which has been spearheading the rebellion in Panem. Katniss eventually agrees to act as "the Mockingjay"—a poster child for the rebellion—but only on the condition that District 13's President Alma Coin vows to grant immunity to all of the past Hunger Games tributes, including her friends Peeta Mellark, Johanna Mason, and Finnick Odair's lover Annie Cresta, and to reserve for Katniss the right to personally kill Panem's President Snow once he is captured. Tasked with starring in rebel propaganda films, called propos, Katniss is unhappily kept out of actual combat until she defiantly participates in a tragic battle at District 8.

Meanwhile, Peeta is being held by the Capitol and forced to defame Katniss and the rebels on live television. During one broadcast, though, he exposes the Capitol's surprise plan to bomb District 13, thus saving many lives during the ensuing explosions but also causing the Capitol to "hijack" him, a process in which he is infused with tracker jacker venom, developing in him a deranged resentment and fear of Katniss. Soon afterward, District 13 leads a successful mission to rescue Peeta and other tributes of the most recent Games, but Peeta immediately attempts to kill Katniss upon their reunion. Therapy improves Peeta's psychological condition over time, but he retains some memory loss and is still prone to violent outbursts toward Katniss.
