The film begins in May 1973 in Phnom Penh, the capital of Cambodia, where a fierce civil war rages between the Cambodian national army and the communist Khmer Rouge, sparked by the fallout from the Vietnam War. Here, Dith Pran (Haing S. Ngor), a Cambodian journalist working as an interpreter for Sydney Schanberg (Sam Waterston), eagerly awaits Schanberg's arrival at the Phnom Penh airport. However, due to unforeseen delays, Schanberg arrives three hours late and, frustrated by Pran’s absence, heads to his hotel via taxi. At the hotel, he meets photographer Al Rockoff (John Malkovich), who is clueless about Pran's whereabouts. They decide to grab a bite at a nearby café when suddenly, an explosion erupts nearby. While Al speculates that a grenade was thrown from a passing scooter, the real nature of the chaos remains obscured.
Pran finally shows up, informing Schanberg of a disastrous incident in the remote town of Neak Leung, where an American B-52 bomber reportedly attacked by mistake. After confirming the grim news with the U.S. Consul, the two rush to find transportation to the scene of devastation. Pran cunningly manages to sneak both himself and Schanberg onto a police boat headed for Neak Leung. Upon their arrival, they are confronted with horrific scenes of destruction and loss, with countless civilians—many of them women and children—tragically affected. Their attempts to capture evidence of two Khmer Rouge operatives being executed by Cambodian army officers result in their arrest. Ultimately, they are released, much to Schanberg’s ire, as he witnesses the international press arriving with the U.S. Army, only to report a heavily sanitized narrative of the tragedy.
Fast forward to April 1975, the atmosphere is tense as international embassies hastily begin evacuating in anticipation of the Khmer Rouge’s takeover of the capital. Schanberg secures evacuation documents for Pran, his wife, and their four children, but Pran insists on staying behind to assist Schanberg in his coverage of the unfolding events. As Pran’s family joins the exodus of diplomats, the Khmer Rouge march into Phnom Penh on April 17, feigning a message of peace while the reality outside reveals brutal conflicts. While attending a makeshift hospital, Schanberg and Rockoff observe the terrifying impact of warfare on civilians, only to be arrested by a group of Khmer Rouge soldiers moments later. Through a mix of courage and quick thinking, Pran manages to bribe an officer, ensuring Schanberg and his friends are released.
The group finds temporary refuge in the French embassy, waiting for the chance to escape. However, the Khmer Rouge demand the handover of all Cambodian citizens, and Rockoff and fellow photographer Swain attempt to forge a passport for Pran. Unfortunately, without a current photograph, their efforts yield a faded illusion of hope. Consequently, Pran is left no choice but to surrender to the Khmer Rouge’s totalitarian regime, as the remaining foreigners are expelled from Cambodia.
Months later, back in New York City, Schanberg embarks on a fervent search for Pran, reaching out to numerous humanitarian organizations and staying in touch with Pran's family in San Francisco. Meanwhile, in Cambodia, Pran finds himself as a forced laborer under the Khmer Rouge’s “Year Zero” policy—a horrifying regression to agrarian life. Surrounded by armed children trained to uphold the regime, Pran endures grueling days in rice fields while feigning ignorance to avoid detection as an intellectual target, especially as the regime systematically eliminates those they consider threats.
Time advances to January 1979, where Schanberg receives accolades for his courageous coverage of the Cambodian plight. While accepting an award, he acknowledges that half the recognition belongs to Pran, but his celebration is interrupted by Rockoff, who vehemently accuses him of failing to do enough to rescue Pran. This accusation deeply resonates with Schanberg, leading him to question his choices and priorities. Through the lens of self-reflection, he admits, “Pran stayed because I wanted him to stay.”
Back in Cambodia, Pran has ascended to a role where he assists a Khmer Rouge prison leader named Phat while largely aiming to protect the innocent—especially Phat's young son. The turmoil escalates when fighting erupts between the Khmer Rouge and advancing Vietnamese forces, eventually leading to chaos and violence around the compound. In the ensuing confusion, Pran seizes an opportunity to escape, aided by Phat’s son who possesses a map leading to safety. However, tragedy strikes as a mine explosion claims the life of Pran’s companion during their desperate flight to freedom, leaving him to continue his escape alone through perilous jungles.
At last, Pran emerges from the jungles to behold a Red Cross camp near the Thai border. In a moment filled with hope, Schanberg, back in New York, learns that Pran is alive and struggles to share the glad tidings with Pran's family. Shortly thereafter, he travels to Thailand to reunite with Pran, who, even amidst their trials, offers a peaceful embrace along with the heartfelt words, “Nothing to forgive, Sydney.” This reunion is beautifully underscored by the timeless melody of John Lennon’s “Imagine,” which plays over poignant images during the closing credits, including real photos of both Pran and Schanberg.
