Lee Gates (George Clooney), a well-known TV financial expert, became famous as the host of the TV financial program "Money Monster". He often makes crazy moves on the show, shouts out investment advice, and introduces the stock market with funny props and sound effects from time to time. However, in fact, he became a money-making expert on Wall Street through insider information. An uninvited guest (Jack O'Connell) lost all his savings because he believed in investment analysis, so he kidnapped Gates and program producer Patty Fenn (Julia Roberts) during the live broadcast of the show. At the same time, people all over the country are watching this life-threatening live broadcast on TV, and this hostage-taking action also reveals a bigger financial manipulation scandal behind it.
