Verbal Kint (aka Keyser Soze?!) narrates 'the story' of what happened after their police lineup, few weeks back, that ultimately leads up to the finale at the ship. Verbal uses a lot of information from the pinups in the room where he is interrogated and forges his story. Like in the first heist pulled, they must have actually pulled the heist. But Verbal reads 'Redfoot' somewhere from the pinups and creates a fence with that character. So my question is which parts of that story actually happened and which were the parts he made up? How far is the story told by Kint to David Kujan true?
It's kind of the point and charm of the film that your narrator is unreliable. All we can know for sure is that a boat was blown up, all of it's passengers were killed and that they were trading people when Keyser Soze was killing many men. Other than that, no other points of the story were qualified as true. There weren't even police reports for the New York's Finest Taxi Service heist. This is a great question. I would even venture to say that it is THE question. But it is totally unsolvable, I'm afraid.
The only portions of the film which were not fabrications of Keyser Soze were:
- The initial sequences showing the arrest of the gang,sans Verbal Kint.
- The conversations between Agent Kujan and FBI Jack Baer concerning Soze.
- The scenes of the ship after the the fire and explosion that destroyed it.
- Agent Kujan's questioning of Verbal Kint
- The scenes in the hospital with the survivor of the carnage at the ship
- The end reveal sequence
It can be safely assumed that the entirety of the film besides the above were all the story created by Kint/Keyser Soze to explain what happened.
