Mr. Thatcher paces in an office dictating to his secretary. He says that on Charles Kane's 25th birthday, he'll become completely independent from the bank and receive the world's 6th largest private fortune.
Charles Kane (now all grown up) writes back to Thatcher saying he's not interested in all the mines or whatever. The only thing he cares about is a little newspaper called The Inquirer, which he'd like to run himself.
Next thing you know, Charles Kane is going after the rich folks of America and using his paper to expose all kinds of corruption.
