Animal World

Plot: the game is set up to lure in poor people hoping to make a quick buck. They're all gathered in a room where they can face off in rock-paper-scissors challenges against each other. Some basic rules (there's a 4-hour time limit, you need to lose all your cards and average a positive win/lose balance) are given, allowing people enough elbow room to cheat, betray, and strategize their way to victory. The film follows Zheng Kaisi, a smart kid whose mother's illness, combined with an old personal trauma, keeps him from realizing his full potential. He gets dragged into the game when one of his friends sets him up, and they both have to pay the price.
