friendly fire

A man in a grey suit holds a gun and stands before a large, circular vault door as a figure in black fires a submachine gun at the door, causing sparks and debris to fly. The scene cuts to a man in a dark, blood-stained jacket standing in a hallway, holding a pistol and looking toward the camera, while the back of the suited man is visible in the foreground. The sequence alternates between these two shots, showing the ongoing confrontation.
