In the year 1939, the story unfolds as Suffolk landowner Edith Pretty hires local self-taught archaeologist and excavator Basil Brown to explore the large burial mounds at her serene estate in Sutton Hoo. Initially, she proposes a payment equivalent to the minimal agricultural wage, similar to what he earned from the Ipswich Museum. However, Brown finds this offer insufficient and negotiates a better deal of £2 a week, which she gladly agrees to.
Despite attempts by his former employers to lure him to excavate a Roman villa they believe to be more significant, Brown holds steadfast, proposing that the mounds might, in fact, date back to the Anglo-Saxon period rather than the more recognized Viking era. As he undertakes his excavation with a few estate assistants, he carefully uncovers the most promising of the mounds. There’s a harrowing moment when a trench unexpectedly collapses on him, but he is thankfully rescued just in time.
As the narrative progresses, Brown spends more time with Edith, a widow facing her own challenges, and her spirited young son, Robert Pretty. While neglecting letters from his own wife, May, he becomes deeply involved in their lives. Edith faces her own health issues, receiving stern advice from her doctor to minimize stress.
One of the pivotal moments occurs when Brown discovers iron rivets from a ship, hinting that the burial site may belong to someone of significant status, potentially a king. Local archaeologist James Reid Moir attempts to join the excavation but is turned away. Instead, Edith brings her cousin Rory Lomax on board to assist. News of their discoveries spreads rapidly, attracting the attention of Cambridge archaeologist Charles Phillips, who declares the site of national importance and takes control of the dig by order of the Office of Works.
As the threat of war looms, Philips enlarges the team, incorporating Peggy Piggott, who goes on to unveil the first distinctly Anglo-Saxon artifact. Although Brown initially retains a position to maintain order at the site, Edith insists on his return to excavating. Ultimately, he unearths a Merovingian Tremissis, a small but significant gold coin from Late Antiquity, leading Philips to officially classify the location as one of considerable historical value.
Philips expresses the desire to send the discovered items to the British Museum, but Edith, concerned over potential damage from air raids in London, declares her ownership rights. An inquest verifies her claim to the ship and its invaluable grave goods; however, as her health deteriorates, her spirit begins to wane.
Meanwhile, Peggy, feeling disregarded by her husband Stuart—who harbors his own secret—embarks on a romance with Rory, but their relationship is cut short as he is soon drafted into the Royal Air Force. In a heartfelt gesture, Edith decides to donate the Sutton Hoo treasures to the British Museum, ensuring that Brown is recognized for his invaluable contributions. Tragically, she passes away in 1942.
Years later, it is revealed in a note that the treasures were hidden in the London Underground during the war and were first displayed—without Basil Brown receiving any recognition—nine long years after Edith's death. It wasn't until recently that Brown was rightly acknowledged for his efforts, and his name now graces a permanent place alongside Edith Pretty's at the British Museum.
