Katniss (Jennifer Lawrence) and Peeta (Josh Hutcherson), who have experienced life and death, have received all the treatment enjoyed by the 74th Hunger Games champions, but their relationship has become awkward. Katniss cannot let go of her former boyfriend Gale (Liam Hemsworth) and even wants to run away with him. Katniss and Peeta are becoming more and more popular with the people, and the fact that they pretend to be a couple has angered President Snow (Donald Sutherland). He and the new game designer (Philip Seymour Hoffman) launched a 25-year "World Class Limited Competition", requiring the selection of one male and female champion from each of the 12 districts to participate, aiming to kill Katniss. In order to protect Katniss, Peeta replaces Haymitch (Woody Harrelson) in the competition, and the pair of "lovers" embark on the journey again. During the competition, the two made allies from different districts. At the same time, Peeta continued to express his true feelings to Katniss, and her attitude towards Peeta also changed. Unfortunately, things were not as they imagined, and only conspiracy was waiting for them.
