Summary from this site:
A nihilistic, erudite hitman, Vincent (Tom Cruise) uses a cab to make his rounds one night in Los Angeles. After Max (Jamie Foxx) learns the truth about the man he's been driving when the first mark falls onto his cab roof from a window after being shot by Vincent, he tries to get out of Vincent's way offering him his cab, but Vincent forces Max to drive him all night.

Eventually Max realizes that the marks are key witnesses for the prosecution in a court case against an organized crime boss. Max must find a way to save himself and the one last victim.
