Lawrence of Arabia

The film is presented in two parts, divided by an intermission.
Part I[edit]
The film opens in 1935 when Lawrence is killed in a motorcycle accident. At his memorial service at St Paul's Cathedral, a reporter tries (with little success) to gain insights into this remarkable, enigmatic man from those who knew him.
The story then moves backward to the First World War, where Lawrence is a misfit British Army lieutenant, notable for his insolence and education. Over the objections of General Murray, Mr. Dryden of the Arab Bureau sends him to assess the prospects of Prince Faisal in his revolt against the Turks. On the journey, his Bedouin guide is killed by Sherif Ali for drinking from his well without permission. Lawrence later meets Colonel Brighton, who orders him to keep quiet, make his assessment, and leave. Lawrence ignores Brighton's orders when he meets Faisal. His outspokenness piques the prince's interest.
Brighton advises Faisal to retreat after a major defeat, but Lawrence proposes a daring surprise attack on Aqaba; its capture would provide a port from which the British could offload much-needed supplies. The town is strongly fortified against a naval assault but only lightly defended on the landward side. He convinces Faisal to provide fifty men, led by a sceptical Sherif Ali. Teenage orphans Daud and Farraj attach themselves to Lawrence as servants. They cross the Nefud Desert, considered impassable even by the Bedouins, travelling day and night on the last stage to reach water. One of Ali's men, Gasim, succumbs to fatigue and falls off his camel unnoticed during the night. When Lawrence discovers him missing, he turns back and rescues Gasimâand Sherif Ali is won over. He gives Lawrence Arab robes to wear.
Lawrence persuades Auda abu Tayi, the leader of the powerful local Howeitat tribe, to turn against the Turks. Lawrence's scheme is almost derailed when one of Ali's men kills one of Auda's because of a blood feud. Howeitat retaliation would shatter the fragile alliance, so Lawrence declares that he will execute the murderer himself. He is then stunned to discover that the culprit is Gasim, the very man whom he risked his own life to save in the desert, but he shoots him anyway.
The next morning, the Arabs overrun the Turkish garrison. Lawrence heads to Cairo to inform Dryden and the new commander, General Allenby, of his victory. While crossing the Sinai Desert, Daud dies when he stumbles into quicksand. Lawrence is promoted to major and given arms and money for the Arabs. He is deeply disturbed, however, confessing that he enjoyed executing Gasim, but Allenby brushes aside his qualms. He asks Allenby whether there is any basis for the Arabs' suspicions that the British have designs on Arabia. When pressed, the general states that they do not.
Part II[edit]
Lawrence launches a guerrilla war, blowing up trains and harassing the Turks at every turn. American war correspondent Jackson Bentley publicises his exploits, making him world famous. On one raid, Farraj is badly injured. Unwilling to leave him to be tortured by the enemy, Lawrence shoots him before fleeing.
When Lawrence scouts the enemy-held city of Deraa with Ali, he is taken, along with several Arab residents, to the Turkish Bey. Lawrence is stripped, ogled, and prodded. He strikes out at the Bey and is severely flogged and possibly raped. He is then thrown into the street. The experience traumatises Lawrence. He returns to British headquarters in Cairo, but he does not fit in.
A short time later in Jerusalem, Allenby urges him to support the general's "big push" on Damascus, but Lawrence is a changed, tormented man, unwilling to return. He finally relents.
He recruits an army that is motivated mainly by money rather than by the Arab cause. They sight a column of retreating Turkish soldiers who have just slaughtered the people of the village of Tafas. One of Lawrence's men is from the village; he demands, "No prisoners!" When Lawrence hesitates, the man charges the Turks alone and is killed. Lawrence takes up the dead man's cry, resulting in a massacre in which Lawrence himself participates with relish. Afterwards, he regrets his actions.
His men take Damascus ahead of Allenby's forces. The Arabs set up a council to administer the city, but they are desert tribesmen, ill-suited for such a task. Despite Lawrence's efforts, they bicker constantly. Unable to maintain the public utilities, the Arabs soon abandon most of the city to the British.
Lawrence is promoted to colonel and immediately ordered home, as his usefulness is at an end to both Faisal and the British. A dejected Lawrence is driven away in a staff car.
