In David Mamet's twisty thriller Heist, Joe Moore (played by Gene Hackman) has a sophisticated plan to get away with the loot rather than splitting it with Mickey Bergman who has reneged on previous deals.
Near the end, most of Bergman's men are killed in a shoot out. But not before Joe's wife is led away by Bergman's nephew having apparently done a deal to tell Bergman where the loot is.
In the final scene it looks like Joe has got away only for the nephew and Joe's wife to catch him at the last minute but, again, Joe gets to live because his wife has, apparently, done a deal with Bergman's nephew. But Joe has double crossed them again. Then the movie ends.
Did his wife know of the final double (or was that a higher multiple) cross?
