Henri Charrière, known affectionately as “Papillon”, represented by Steve McQueen, is a skilled safe-cracker in 1933 France, branded with a butterfly tattoo on his chest. Wrongfully accused of a murder he did not commit, he finds himself sentenced to life imprisonment in the brutal penal system of French Guiana in South America. During his harrowing journey, he crosses paths with Louis Dega, portrayed by Dustin Hoffman, a notorious forger and embezzler who believes that his wife will orchestrate his escape. Despite initial reluctance, Papillon offers to protect Dega in exchange for financial backing for their escape plan, especially after a frightening incident on the transport ship shakes Dega's confidence.
Upon arriving in the hellish landscapes of St Laurent, where 40% of inmates perish in the first year alone, Papillon learns the grim realities of life within the vast jungle prison, cut off from civilization. Here, he encounters fellow prisoner Julot (Don Gordon](/actor/don-gordon)), who educates him on the harsh rules governing prison life, which includes punitive measures for escape attempts—two years in solitary for the first, and five added for subsequent attempts. The oppressive warden, William Smithers, represents the unyielding system they are forced to navigate.
In a twist of fate, Dega manages to bribe a guard and keeps the pair safe from the dreaded work camps, although they are ultimately sent to labor at the Kilo-40 timber yard. In this nightmarish existence, prisoners are subjected to inhumane conditions: subpar food, inadequate living spaces, and brutal treatment. Despite it all, Papillon forges a bond with Dega and they plot their escape.
Papillon, seizing a rare opportunity, convinces a butterfly trader to assist them in arranging a boat. Unfortunately, their plan falters when Papillon is captured after defending Dega from a vicious guard and finds himself sentenced to solitary confinement on a desolate island. Enduring deprivation and punishment, where he even resorts to eating insects, Papillon remains resolute, unwilling to betray Dega.
Eventually freed, Papillon recovers and meets Dega again, who has gained favor in the prison system as the chief clerk. However, the passage of time weighs heavy on Papillon, who feels a sense of urgency to escape. He recruits fellow inmates, including Clusiot (Woodrow Parfrey) and Maturette (Robert Deman), in a daring escape plan that culminates in a chaotic attempt to flee the prison.
During their escape, the precariousness of their situation escalates as Dega injures himself, and the trio inadvertently exposes the betrayal of their guide, Pascal (Val Avery), leading to a tense pursuit. They manage to evade capture with help from a local trapper, finding temporary refuge in a leper colony where they acquire a seaworthy boat.
The journey is fraught with peril, culminating in a dramatic confrontation with soldiers, leading to the capture of Dega and Maturette, while Papillon narrowly escapes. Finding solace among a native tribe and experiencing a moment of love, he soon discovers that freedom comes at a steep price, as he is betrayed and recaptured while seeking refuge.
Back in the confines of French Guiana, he is subjected to another stint in solitary, emerging battered and aged, only to locate his friend Dega, who has succumbed to despair. As they plot their next escape from the cliffs of Devil's Island, Dega’s apprehension leads him to plead with Papillon to abandon the plan. However, driven by the hope of liberation, Papillon jumps into the sea, where he finally finds the currents of freedom.
The story concludes with a solemn narrator hinting at Papillon's ultimate escape from the unyielding grip of the prison system, while the prison itself, a relic of torture, fades into history. Though the film diverges in various ways from the original book, what remains is a tale of resilience and an indomitable spirit against the crushing weight of wrongful incarceration.
