In Christopher Nolan’s *Dunkirk* (2017), the plot is set in motion through three distinct, non-linear timelines that converge at the film's climax. Each timeline begins with specific actions that establish the stakes of the evacuation (Operation Dynamo).
### 1. The Mole (Land): One Week
The film opens with a visceral sequence on land that immediately establishes the desperation of the trapped Allied forces.
* **The Action:** A young British private named **Tommy** and five fellow soldiers are seen wandering through the abandoned, eerily quiet streets of Dunkirk. As they scavenge for food and water, German propaganda leaflets—telling them they are surrounded—flutter down from the sky.
* **The Catalyst:** Suddenly, German soldiers (who remain unseen) open fire from the windows. Tommy is the only one who survives the ambush. He sprints toward the French-held perimeter, barely making it through to the beach.
* **The Plot Motion:** Once on the beach, Tommy realizes the scale of the disaster: 400,000 men are waiting for ships that aren't coming fast enough. He encounters a soldier named **Gibson** burying a body, and together they attempt to jump the evacuation queue by carrying a wounded man on a stretcher toward the "Mole" (the stone breakwater used as a makeshift pier).
### 2. The Sea (Water): One Day
The second thread begins in Weymouth, England, and represents the civilian response to the crisis.
* **The Action:** **Mr. Dawson**, a civilian mariner, is seen preparing his yacht, the *Moonstone*, for sea. The Royal Navy has begun **requisitioning private vessels** to cross the English Channel and reach the shallow waters of Dunkirk where larger destroyers cannot navigate.
* **The Catalyst:** Instead of allowing the Navy to commandeer his boat, Dawson decides to pilot the *Moonstone* himself. He is joined by his son **Peter** and a local teenage hand, **George**, who impulsively jumps aboard just as they cast off.
* **The Plot Motion:** Their journey starts the plot in motion when they depart ahead of schedule, heading directly into a war zone. Their first major action at sea is the rescue of a shell-shocked soldier (Cillian Murphy) sitting atop a wrecked ship, which introduces the psychological trauma that permeates the film.
### 3. The Air (Air): One Hour
The third thread starts with the Royal Air Force (RAF) providing the thin line of defense against German bombers.
* **The Action:** Three Spitfire pilots—**Farrier**, **Collins**, and their **Leader**—are shown flying in formation across the English Channel toward the French coast.
* **The Catalyst:** The "action" begins with a technical and tactical exchange over the radio. The Leader instructs the others to "save their fuel" and provides their mission objective: protect the ships at the Mole and the men on the beach from the Luftwaffe.
* **The Plot Motion:** The plot moves forward as they cross the coastline and Farrier realizes his fuel gauge is broken after a brief skirmish. He must now track his fuel consumption by hand on his dashboard, creating a ticking clock for the rest of his narrative.
