Tense Dialogue on a Rolling Car Ferry

Stage 1: The vehicle deck of an overnight car ferry mid-crossing, lit by yellow deck lamps that swing with the roll of the ship. Rows of cars lashed down under chains, sea noise coming through the hull. Two men stand in the gap between two parked trucks, one in a soaked wool coat, one in a company windbreaker holding a clipboard. The deck rolls and every chain on the deck takes up its slack at the same moment. Ends with both men bracing a hand against a truck flank as the roll peaks. Stage 2: The man with the clipboard does not look up from it and says, "몇 시에 내려?" The other man's mouth stays closed. The ship rolls back the other way and one badly secured sedan behind them shifts half a meter until its chains snap taut. Ends with that sedan settled at an angle and both men still squared up to each other. Stage 3: The man in the wool coat says, "나는 안 내려." Only his mouth moves. The other man finally looks up from the clipboard. Neither of them moves after that. Ends locked on the two of them with the deck lamps swinging across their faces and the chains still ringing. Camera: locked low in the gap between the two trucks at chest height, close enough to hold both faces, and it never moves while the entire frame rolls with the ship. Continuity: the same coat, windbreaker and clipboard throughout, the same cars in the same places apart from the one sedan that shifts, and the roll never reverses direction inside a stage. Audio: clean lip-synced Korean, a hull working in a swell, dozens of chains loading and going slack together, one sedan's suspension complaining, deck lamps creaking on their mounts, an engine room a long way below. No subtitles, nothing scored.
