A male voice speaks the line 'a gun with one bullet' over about four seconds, low and serious with slow, deliberate pacing and weight on each word. There is no music or background noise behind it. The delivery feels tense and final, turning a simple statement into a standoff warning where a single chance decides everything and there is no room for a second try.
