Help me, I missed the ending!

I don't know exactly when you stopped watching , But I'll fiil you in.

Brewster goes with Walker to Elcatraz to get him the money , Brewster stands in the middle waiting for the helicopter to land , he takes the money while Walker is out of his sight.

He calls Walker but then Brewster is shot. He wasn't shot by Walker , who hides in the shadows.

The guy who made the deal with Walker to help him get the organisation , comes out and with him comes the sniper who shot Carter and Stegman. It turns out that he is Fairfax , and he used Walker to take control of the organisation , he calls Walker to take the money and join him , for he has been looking for someone like him for a long rime.

Walker only listens and goes away into the darkness.

The End

The movie's "martini" ends at Alcatraz (correct spelling). Used to be a federal prison, once housing the "infamous" Al Capone.

There are many deliberate continuity lapses in "Point Blank". Remember Walker's confrontation with his his wife, her suicide, then him standing by the bloody mattress? I believe Walker was either still at Alcatraz, dieing, dreaming about the rest of the movie; or he was an "avenging angel," as was Clint Eastwood in "High Plains Drifter."
