In a city where neon‑lit streets conceal a labyrinth of hidden loyalties, Thee carries the weight of a family mystery that has haunted him since childhood. Raised in a modest car‑repair shop by an uncle who shielded him from a past he never chose, he discovers that his parents were once undercover detectives whose lives were cut short by an unknown force. The revelation ignites a relentless drive to uncover the truth, pulling him away from the familiar hum of engines and into the shadowed corridors of the criminal underworld.
Determined to trace the source of his loss, Thee infiltrates a dangerous organization that operates by an unyielding assassin’s code—focus, unwavering vigilance, and merciless resolve.

Spoilers ahead
Thee Dan Chupong and his brother Than are two young men raised by their uncle, a former detective who now runs a small car repair shop. Their curiosity about a locked room in the workshop grows until one evening they wheedle their uncle into letting them in, getting him drunk enough to sneak inside. There they uncover clues that their parents were also undercover detectives who were killed in an ambush by an unknown attacker. Their uncle, Ping Lumpraploeng, had once sworn to shield the family from that dangerous life and to raise the brothers away from the old profession he himself walked away from.
Learning the truth sets Thee on a singular path: he vows to uncover who killed their parents, while Than stays behind at the shop, training in martial arts by watching old VHS tapes in a back room. The brothers drift onto divergent roads—one chasing justice, the other honing his skills in seclusion—yet both carry the weight of a past that refuses to stay buried.
To move this quest forward, Thee joins a ruthless team of killers, intent on climbing the ladder to the person who ordered the deadly hit. Along the way he is hired to protect Ploy, Nisachon Tuamsoongnuen, a young woman with dyed blonde hair who is the granddaughter of a powerful businessman. The assignment seems straightforward, but the mission soon spirals as Thee discovers that Ploy is the real target and that he has been set up to take the blame for her murder. He is double-crossed during the job, yet his tenacity and fighting spirit push him to rescue Ploy and lead them on the run.
As they flee, the pair heads back to his family home, where a hidden network of power and corruption begins to unravel before them. The danger is no longer just a single hit; it’s a systemic force that threatens anyone tied to the brothers’ past. The uncle’s murder deepens the resolve of Thee and Than, and the two brothers—now bound to a frightened yet determined Ploy—discover that they must fight back not just for revenge but for justice and truth.
Facing assassins and a maze of enemies, Thee, Ploy, and their unlikely ally Si Fu, the Chinese doctor played by Winston Omega, craft a plan to bring the hidden power brokers into the light. The path is fraught with peril, but the trio’s alliance strengthens as they uncover the roots of the conspiracy and challenge those who pulled the strings behind their parents’ deaths. In the end, Thee’s personal quest for justice intersects with a broader battle against corruption, forcing the brothers to confront a dangerous truth and to fight for their family’s legacy with renewed courage and resolve.
