Netflix’s four-part miniseries Death by Lightning revisits the remarkable yet brief presidency of James Garfield, America’s 20th president, and the disturbing story of his assassin, Charles Guiteau.

The Nteflix series, starring Michael Shannon and Matthew Macfadyen, explores how idealism, obsession, and political corruption collided in one of the most shocking episodes in US history.

The rise of an unlikely president

The story opens at the Republican National Convention of 1880, where Garfield, intending only to nominate another candidate, delivers a powerful speech that propels him into the presidential race.

A self-made man from rural Ohio, Garfield’s life was a testament to perseverance — he worked as a janitor, preacher, and Civil War general before entering politics. His presidency, however, lasted only four months before tragedy struck, making it one of the shortest in American history.

The assassin’s descent into madness

The series’ second arc follows Charles Guiteau, a delusional drifter and failed writer whose obsession with Garfield turns deadly. Convinced he was destined for greatness, Guiteau demanded a government position as a reward for Garfield’s election victory.

When ignored, his delusions deepened. Believing divine forces had chosen him to “save the Republic,” Guiteau purchased an ivory-handled revolver and shot Garfield at Washington’s Baltimore and Potomac train station in July 1881. Garfield succumbed to his wounds two months later at age 49.

A chilling portrayal of ego and obsession

Macfadyen’s portrayal of Guiteau blends absurdity and menace — a man both pitiful and terrifying in his hunger for validation. Shannon’s Garfield, by contrast, radiates dignity and reformist zeal, representing the best of American democracy undone by its own dysfunction.

The series juxtaposes Garfield’s moral integrity against Guiteau’s manic self-importance, offering a psychological study of ambition gone awry.

Corruption and power in Gilded Age politics

Supporting performances by Nick Offerman as Vice President Chester Arthur and Shea Whigham as power broker Roscoe Conkling expose the deep-seated corruption of Gilded Age Washington.

Arthur’s reluctant transformation from party loyalist to reform-minded president mirrors Garfield’s unfulfilled vision, highlighting the complex legacy left in the wake of assassination.

A courtroom spectacle and a nation in shock

Guiteau’s 1882 trial became one of the first American media circuses. Claiming he acted on “divine command,” he turned the proceedings into a platform for his delusions.

Despite his erratic behaviour, the jury found him guilty, and he was executed by hanging in June 1882. His final words — proclaiming himself a martyr — cemented his infamy.

A reflection of modern disillusionment

Though set in the 19th century, Death by Lightning resonates today, exploring themes of alienation, ego, and violence. It reflects how unstable ambition and the hunger for recognition can twist individuals — and even nations — into tragedy.

Garfield’s legacy endures as that of a visionary reformer silenced too soon, while Guiteau remains a chilling reminder of what happens when delusion meets opportunity.

Fact meets cautionary tale

Netflix’s retelling succeeds not as mere historical drama, but as a cautionary reflection on power, faith, and fame.

Through its haunting performances and meticulous period detail, Death by Lightning restores a forgotten chapter of American history — one where madness, morality, and politics collided with fatal consequence.
