Maek [Chaiwat Thongsaeng] is a lone gunman who takes on a dangerous task: kidnap a police informant named Iht. When he brings Iht to the so-called “hit house,” his conscience shifts. He refuses the order to kill Iht, arguing that the informant might not be the real enemy and that his true target are the mobsters who hired him. Instead, Maek turns his weapon on the enforcers, triggering a brutal shootout that leaves him wounded. Iht grabs Maek’s gun and together they fight their way out of the mobsters’ headquarters on Maek’s motorcycle.
Back at a rooftop hide-out, Maek orders Iht to leave, but Iht won’t abandon him. He tends to Maek’s wounds, and a quiet, complicated attraction begins to grow between them. Maek, though drawn to Iht, keeps his feelings hidden while Iht offers genuine tenderness and care for his would-be killer.
One night, during a bath, Iht kisses Maek, and the moment unfolds into a deeply intimate connection. The next day, a conflicted Maek insists Iht should go away. Iht returns to his fiancée Sai Chadatirud Lertaveesin, but his heart isn’t in the engagement anymore. He spends his days pining for Maek, while glimpses of Maek’s life linger in his thoughts. He learns about Maek’s family from Maek’s brother Mhok Nakarin Kangwanchokechai and their mother Uthumporn Silaphan. Mhok is HIV positive due to abuse by their stepfather, and their mother is dying of AIDS.
Maek stays elusive, leaving signs that he’s nearby. He eventually visits his mother and brother; Iht corners him at the entrance to the building, declares his love, and the two share a kiss again, though Sai watches from a distance, unaware of the depth of their bond.
Maek’s dream is a simple one: to take his mother and brother away from Bangkok to the mountains of Mae Hong Son Province. But tragedy strikes when Maek’s mother overhears that Mhok prostituted himself to survive after contracting AIDS. She hangs herself, and as they try to move her body, a sniper’s bullet wounds her, clearly aimed at Maek.
The Mob continues to close in. Maek decides to hunt them first and succeeds in killing them. Mohk informs Iht of Maek’s plan, and Iht heads to the capo’s house to intervene but arrives too late. He is wounded when the capo’s wife shoots at a clock that shatters in his face, a brutal misdirection of violence.
At the railway station, Maek meets his brother to leave Bangkok for good, but police intercept him. Mhok becomes the sole witness to Maek’s arrest. Years pass. Iht visits Maek in prison and learns that he was blinded in the final gunbattle with Maek’s former boss. Mhok dies in a Hospice in Lopburi, worn down by illness. Eventually Maek is released, and Iht greets him with hope for a new life together. Yet, just as they stride toward a brighter future, Maek is shot dead by an unseen assassin. Iht, now blind, collapses over his lover’s body, crying out his name again and again.
In time, Iht regains his sight and finds a long-ago video Maek recorded, revealing—through a quiet confession—that he had loved Iht all along and would love him until his last breath. The truth, once hidden, finally shines through the years they spent apart.
