Margin Call (2011)

Junior employees Seth Bregman and Peter Sullivan, along with senior trader Will Emerson, witness mass layoffs at their investment bank. Peter receives a USB drive from a fired employee containing important information about the firm's risk. They discover that the firm is at risk of bankruptcy due to overleverage and excessive trading. Throughout the night, the employees attend meetings with executives and devise a plan to sell off toxic assets. The CEO's plan will spread the risk and destroy the firm's relationships. Eventually, the employees achieve a benchmark to receive large bonuses but face the consequences of their actions. The CEO offers Rogers a future opportunity, and the film ends with Rogers burying his dog.
