Plot Summary

Set in Detroit and the Brazilian Amazon from the late 1920s through the mid-1940s, the novel follows an ensemble of characters whose lives intersect with Henry Ford's industrial empire during economic collapse, labor upheaval, racial violence, and world war.

In late 1927, the Ford Motor Company unveils its Model A. Smitty, a reporter for the Detroit Free Press, covers the launch while needling Edsel Ford, the company president, and Ernest Liebold, a Ford executive who once fired Smitty from the Ford-owned Dearborn Independent newspaper before its worst anti-Semitic campaigns. Riding through the Rouge River plant, the elderly Henry Ford overrules Edsel's order for new coke ovens, instructing Harry Bennett, head of his Service Department (an internal security and enforcement operation), to tear them out once finished, humiliating his son. Ford's obsession with vertical integration, controlling every raw material from wood to rubber, drives him to purchase an enormous tract of Brazilian jungle for a rubber plantation called Fordlandia.

In the Amazon, João, a seringueiro (rubber tapper), is hired at triple his wages and moves his wife, Beatriz, and young son, Flavio, to the plantation. Bennett summons Jim Rogan, a sawmill foreman at Ford's Pine Camp lumber operation in Michigan's Upper Peninsula, fires a pistol at a wall map of Brazil, and orders Jim to clear jungle. Jim leaves his wife, Norma, and daughter, Kerry, behind with no knowledge of rubber.

At the Rouge, Kaz Pilsudski, a Polish-American assembly-line worker, endures speedups while worrying about his infant daughter, Sonia, whose developmental condition doctors want to observe and which is later identified as cerebral palsy. Zeke Crowder, a Black foundry worker, pours molten steel in extreme heat, suspecting the line is accelerating without extra pay. Zeke lives with his wife, Mavis, and their children in Inkster, a struggling Black village outside Detroit. On Hastings Street in Detroit's Black Bottom neighborhood, Rosa Schimmel, a young Jewish activist, lives with her father, Asher, injured by police during labor organizing in Chicago, and her brother, Ira. Rosa throws herself into the Communist Party and tenant protests with her personal byword: "Forward!"

Jim's arrival in Brazil begins a years-long ordeal. The clearing is chaotic and disease is rampant. Two traders sent upriver have been bartering company cash and goods for rubber seeds with indigenous Mundurucú people rather than following company policy. Jim fires them, secures the seedlings, and hires Conceição (Connie), a young local woman, as a cook. Norma and Kerry eventually arrive, Norma eyeing Connie with suspicion.

In Detroit, Norma's cousin George warns that the stock market crash has hit her savings and urges immediate withdrawal. Ford announces a raise to seven dollars a day while privately planning mass layoffs. Kaz's father, Prokop, is fired from the Rouge without explanation after nearly twenty years. Jerry Buckley, a popular radio host who helps drive the recall of the Klan-backed Mayor Bowles, is assassinated in the LaSalle Hotel lobby, a crime never solved.

At Fordlandia, resentment among Brazilian workers over regimented schedules and mandatory mess hall dining erupts when a militant worker called Gaúcho sparks a food riot that destroys equipment and buildings. Jim evacuates the American families upriver, and soldiers restore order. The Company establishes a second plantation called Belterra on better land, where Jim takes charge.

Bennett consolidates power through alliances with Detroit gangsters, offering Chester "Big Chet" LaMare a dealership and commissary concessions in exchange for spreading the word that kidnapping anyone in the Ford family will bring lethal retribution. He later uses other underworld contacts to maintain a climate of fear. Diego Rivera, commissioned by Edsel to paint murals at the Detroit Institute of Arts, tours Greenfield Village, Ford's historical museum and educational center, and the Rouge plant, finding in the assembly lines the subject for his monumental Detroit Industry murals. The unveiling scandalizes Detroit's elite, but Edsel protects the work.

In March 1932, thousands of unemployed workers march toward the Rouge to demand jobs and relief. Rosa marches alongside Joe York, a young Communist organizer. When the marchers cross into Dearborn, they are met with tear gas, fire hoses, and gunfire. York is shot; Rosa helps rush him to Henry Ford Hospital, where he dies. Four marchers are killed. Bennett responds by expanding the Service Department.

The United Auto Workers (UAW) union gains momentum. The 1937 Battle of the Overpass sees Bennett's men brutally beat Walter Reuther and other union leaders on the Miller Road overpass as photographers capture the attack. Rosa distributes flyers from traffic islands while Kaz, passing in a company informer's car, rolls up his window. Kaz is later fired and reinstated after the Labor Board intervenes; he and Rosa become allies at union meetings. In 1938, Ford accepts the Grand Cross of the German Eagle from the Nazi government, deepening controversy. Rosa is eventually expelled from the Communist Party for her independence of thought but continues volunteering with the UAW.

Kerry and Flavio grow close at Belterra, exploring the jungle, teaching each other their languages, and sharing a first kiss while picking caterpillars off rubber trees, a relationship both sets of parents oppose. Kerry rescues an orphaned squirrel monkey she names Jocko. Norma volunteers at the hospital under Nurse Esther Kline and discovers a vocation in nursing.

In April 1941, a spontaneous walkout sweeps the Rouge. Kaz is among the thousands who stream out of the gates. Inside the foundry, Bennett arms the mostly Black workforce and orders them to charge the picketers. Reverend Charles Hill, pastor of the Hartford Avenue Baptist Church and a UAW ally, addresses the workers through a loudspeaker, urging them not to serve as strike-breakers. Zeke, whom the workers regard as an informal leader, leads the foundry workers out. The National Labor Relations Board (NLRB) supervises the subsequent vote: The Congress of Industrial Organizations (CIO)-backed UAW wins seventy percent. Ford, pressured by his wife Clara's threat to leave him and daughter-in-law Eleanor's threat to sell her stock, signs a contract that includes automatic dues deduction.

After Pearl Harbor, the Rouge converts to war production. Kaz's wife, Molly, rivets ball turrets on B-24 bombers at the Willow Run factory, while Kaz stamps aluminum fuselage parts. Zeke's eldest son, DeWitt, enlists and joins the 761st Tank Battalion, a Black armored unit. The Sojourner Truth crisis, a violent confrontation over a government housing project for Black families near a white neighborhood, and the catastrophic Detroit race riot of June 1943 tear the city apart. Zeke's younger son, Alvin, is killed in the rioting. Mavis finds his body at the county morgue, escorted by Cedric, a Garveyite street preacher and follower of Marcus Garvey's Black nationalist movement.

Edsel Ford dies of stomach cancer in May 1943 at forty-nine, his health undermined by years of stress under his father's domination. Bennett tries to seize control by having the aging and confused Henry Ford sign a codicil to his will, placing the Company under a Bennett-controlled board. When John Bugas, a former Federal Bureau of Investigation agent now working for Henry Ford II, Edsel's eldest son, demands the document, Bennett burns it. Ford resigns and his grandson takes over. Bugas follows Bennett to his office and draws his pistol when Bennett reaches for his own gun, ending Bennett's reign.

In the closing movements, Jim, believed drowned when his launch capsizes in rapids, reappears in a Mundurucú canoe just as Norma prepares to leave Brazil. Kerry departs for teachers' college in Kalamazoo, Michigan. Smitty encounters an aged, confused Ford alone in Edison's laboratory at Greenfield Village, where Ford reflects that he never invented anything but only connected ideas. In the final scene, Flavio and João pull up abandoned rubber trees at the shuttered Fordlandia. Flavio, now a strong young man educated in the Ford school, demonstrates his English by singing "I Got a Gal in Kalamazoo."
