It is from the film "The Usual Suspects" released in 1995.
The character in the film has somewhat attained underground cult status because the Soze character itself was a made up alter ego for a simpler , cunning unassuming criminal who is similar.
Flash-backs and flash-forwards a la Pulp Fiction capture the action of the story told to the police by one of the criminals, Verbal (Kevin Spacey). Claiming that the five men were threatened by Kobayashi (Pete Postlethwaite), the lawyer of the devil Keyser Soze, Verbal says that they were forced to pull off the high risk job or else their loved ones will be killed
The twist in the plot is that nobody knows who Keyser Soze is. So the question that the criminals, the police and the movie audience ask is "WHO IS KEYSER SOZE?"
Verbal insists that he is a Hungarian drug lord who let his family be killed rather than surrender to an opposing drug force.
In revenge, Keyser Soze killed the families of the men who threatened him. He is never seen by anyone again, yet he continues to communicate through his lawyer.
I refuse to give away the answer to the question, "Who is Keyser Soze?" Every audience member has to try to figure out the mystery for themselves. Only in the last minute of the film is the answer finally revealed
