The First World War brought about the collapse of the Ottoman Empire, which had dominated the Middle East for five centuries. This significant shift opened the door for colonial powers to assert their control, with Britain seizing Egypt in 1914. During this time, Winston Churchill (Christopher Fulford), the defense minister, strategizes how Britain can outmaneuver both the Russians and French to secure influence over Iraq and Kuwait. However, he is confronted with the challenge of navigating the ambitions of Ibn Saud, who seeks to establish his own nation. Amidst this complex backdrop, Churchill realizes the glaring lack of intelligence about the local tribes and their rulers, relying heavily on the insights of Gertrude Bell.
In 1902, Gertrude Bell (Nicole Kidman), raised in a wealthy British family—parented by her mother Florence (Jenny Agutter) and father Hugh (David Calder)—feels unfulfilled by the monotonous and privileged social life of the London elite. Yearning for purpose, she joins her uncle Frank Lascelles (Mark Lewis Jones) in Tehran, where her curiosity about the Near East awakens. Accompanied by her cousin Florence ([Holly Earl]), Gertrude not only discovers the region but also forms a romantic bond with Henry Cadogan (James Franco), an embassy worker who introduces her to the enchanting world of the Orient.
As their relationship blossoms, Gertrude learns that Florence harbors feelings for Henry, complicating matters further. Despite the arrival of joy with a shared kiss, their love story is cut tragically short when Gertrude's parents object to Henry due to his perceived lack of suitability. Heartbroken, Henry succumbs to despair and takes his own life, leaving Gertrude devastated. Determined to honor his memory, she immerses herself in the exploration and documentation of the Near East.
By 1906, Gertrude finds herself in Amman, Jordan, where she encounters Charles Doughty-Wylie (Damian Lewis) and Mark Sykes (Nick Waring). Mark advises her against venturing into the desert, fearing it could incite Turkish anger, but undeterred, Gertrude recruits Fattouh ([Jay Abdo]) to guide her. She ventures deeper into the desert, visiting the British excavation site at Petra, where she meets R. Campbell Thompson ([Michael Jenn]) and his assistant, the legendary T. E. Lawrence (Robert Pattinson).
Recognizing the imminent disintegration of the Ottoman Empire, Gertrude anticipates the emergence of an Arabic nation amid chaos. As her journey continues, she reaches Damascus and plans an audacious expedition to Jabal-Al-Druze, a territory that has remained isolated for decades. On entering, she finds herself captured by the fiercely protective Druze and connecting over a shared appreciation for poetry with their Sheikh (Assaad Bouab).
After three weeks, she departs to explore Hayri, a strictly off-limits area. Despite attempts by Richard ([Anas Chrifi]) to enlist her as a spy, Gertrude firmly stands her ground. As the political landscape unfolds, and with the backdrop of war between Ibn Rashid and Ibn Saud, Gertrude's resolve is tested. Ultimately, she is briefly imprisoned by Emir Rashid's family during her quest for knowledge.
Understanding the shifting tides of power, Gertrude predicts that Ibn Saud will ascend as the new ruler of Arabia. Returning to Damascus, she rekindles her connection with Richard, who vows to divorce his wife, Judith ([Sophie Linfield]). By 1915, Gertrude finds herself at the British Arab Bureau in Cairo, her wealth of knowledge about tribal dynamics instrumental in delineating the borders for future kingdoms of Iraq, Jordan, and Saudi Arabia. Conclusively, her expertise leads to Ibn Saud taking the throne of the newly formed Kingdom of Saudi Arabia.
As the war rages on, tragedy strikes again with Richard's death during the Battle of Gallipoli. Gertrude Bell's legacy is remembered even after her passing in 1926, when she is laid to rest in Baghdad. Her deep understanding of the Bedouin tribes solidifies her place as a foreigner who truly comprehended their ways.
