Plot
Corporal John Bramble is the sole survivor of a British tank crew after Erwin Rommel and his Afrika Korps capture Tobruk in June 1942 and pursue the British into Egypt. He stumbles across the North African desert into the town of Sidi Halfaya, where he finds the Empress of Britain, a small, isolated hotel owned by Farid. The only other employee is the French chambermaid Mouche, as the cook fled with the British and the waiter Davos was killed the night before by German bombing.
Farid hides the now-unconscious Bramble when the swiftly advancing Germans take over the hotel to use as headquarters for Field Marshal Rommel and his staff. Bramble assumes the identity of Davos to save himself. When Rommel summons him to a private chat, Bramble is stunned to discover that Davos was a valued German spy, but manages to play along. He learns that he is to be sent to Cairo next.
Later, he steals a pistol from genial, music-loving Italian General Sebastiano, planning to serve the field marshal a bullet rather than coffee the next morning. Not wanting trouble, Mouche steals the pistol and waits on Rommel herself. When some captured British officers are brought to the hotel for a luncheon with Rommel, one of them (a past guest) realizes that Davos has been replaced. Bramble privately explains who he is and what he plans to do. The officer orders him to use his position of trust to gather military intelligence instead.
At the luncheon, Rommel teases his guests, allowing them to ask him twenty questions about his future plans. Bramble listens with interest. From the conversation and later remarks by Rommel, he eventually deduces that the field marshal, disguised as an archeologist before the war, had secretly prepared five hidden supply dumps, the "Five Graves to Cairo", for the conquest of Egypt. The final piece of the puzzle (their locations) falls into place when Bramble realizes that Rommel's cryptic references to points Y, P, and T refer to the precise locations of the letters of the word "Egypt" printed on his map.
Meanwhile, Bramble and Mouche clash. She despises the British, believing they abandoned the French, including her two brothers, at Dunkirk. He in turn becomes disgusted at how she plays up to the Germans. As it turns out, Mouche's motives are not mercenary; she pleads with Rommel to release her wounded soldier brother from a concentration camp. He is unmoved, but his aide, Lieutenant Schwegler, is more appreciative of her charms. He pretends to help her, showing her fake telegrams to and from Germany.
That night however, when everyone takes shelter in the cellar during an Allied air raid, Schwegler discovers the body of the real Davos (identified by his clubfoot), uncovered by the bombing. In the noise and confusion of the raid, Schwegler chases Bramble through the darkened hotel, before Bramble kills the German and hides the body in Mouche's part of the servants' room. When Mouche finds out, she threatens to unmask him. However, she has a change of heart. Schwegler's body is soon found, and Rommel accuses her of killing his aide when she discovered he was lying about trying to get her brother released. To protect Bramble, Mouche confirms this. Bramble leaves for Cairo, but arranges for Farid to present evidence the next day at Mouche's trial that "Davos" committed the crime.
Bramble's information allows the British to blow up the dumps and thus thwart Rommel's plans, culminating in the Second Battle of El Alamein. When Bramble returns to Sidi Halfaya in triumph with his unit, he learns the Germans executed Mouche, even though she was exonerated of Schwegler's murder, because she would not stop saying that the British would be back. Bramble takes the parasol he bought her in Cairo, something she always wanted, and places it to provide shade for her grave.
