The movie is about the 2008 financial meltdown in US and the bailout of the banks by then Treasury Secretary Henry Paulson. The fulcrum of the story is about how Henry Paulson handled the tough situation. As citizens and laymen we expect our Federal Bankers and Finance Ministry to be experts on Economy and know better. The movie shows how they are caught off-guard and try throwing various things and see which one sticks. What I found surprising in the plot is the complete absence of any reference to then US President George Bush. The administration that Henry Paulson was part of, was headed by George Bush and I find it surprising that you can tell the story without his appearance even once.
From a business perspective the message you can take away from the movie is that you need to raise money when you don’t need it, as you won’t be when you desperately need to.
