Episode 4 of "4Minutes" unfolds with the Chief urging Win to expedite the DNA testing in the second riverfront homicide case. Win promptly contacts the forensics team and learns that the blood spattered on the rock belongs to the second victim, while the fingerprint embedded within belongs to one Anuwat Warindej. Win's face contorts in shock, just as his phone rings — it's Tonkla.
Elsewhere, Tyme speeds off abruptly, leaving Great thoroughly perplexed and deeply concerned. As Great catches up with Korn, who is visibly bleeding and bent on pursuing Tyme, he decides to guide Korn to the hospital instead. The subsequent day, the hospital's winding corridors witness Den observing Great tirelessly combing through every corner in search of Tyme. His relentless quest finally brings him to an operating room, where he patiently waits for hours, his eyes fixed on the door, until Tyme finally emerges.
When they finally confront each other, Great confronts Tyme with a mixture of anger and confusion. However, the conversation veers sharply in an unforeseen direction. Tyme uncovers a devastating revelation: Great's parents, the Sriwats, were scammers whose actions indirectly contributed to the untimely demise of Tyme's parents. His inquiry about Nan only deepens Great's bewilderment. Convinced that Great's claimed ignorance is merely a feigned obliviousness, Tyme storms away in a fury of anger.
Suddenly, a dizzying wave washes over Great, and he finds himself inexplicably transported four minutes back in time, to the precise moment Tyme steps out of the operating room. Seizing this unexpected opportunity, Great promptly proposes to help in finding Nan.
In parallel, Win lends his support to Tonkla during his brother's funeral. An unseen observer trails Win, prompting him to confess that he hasn't ceased investigating Tonkla's brother's case. He theorizes that the perpetrator hails from an influential family intent on quashing his investigations and possibly targeting the victim's sibling as well. To safeguard Tonkla, Win offers to move in with him until the mystery is unraveled. Overjoyed, Tonkla wasted no time in flirting with Win. However, their moment is cut short by Korn's arrival outside. Tonkla hastily hides Win and assumes a casual demeanor. Korn, initially apologetic for his absence, attempts to impose himself physically on Tonkla, who remains nonchalant. Upon learning of Tonkla's brother's demise, Korn shifts gears, offering to assist in the investigation. Yet, Tonkla, irritated by Korn's unpredictable behavior, throws him out. Win appears disturbed, but Tonkla swiftly returns to their foreplay. Post-coital, Win pretends slumber while Tonkla gazes at a cat collar, his mind drifting back to happier times with Korn.
In a poignant flashback, we witness Korn as the older, influential senior in Tonkla's high school life. Tragedy strikes when Tonkla's cruel family takes the life of his beloved cat, prompting him to solemnly bury it on school grounds. Korn, stumbling upon Tonkla's distressed state, offers him the cat's collar as a keepsake, a token of remembrance. Furthermore, he gifts Tonkla his senior ribbon, a symbol of protection against school bullies. Their bond deepens into romance, with their initial encounter being tender and filled with declarations of love. Korn stands as a beacon of support for Tonkla, aiding him and his brother in escaping the clutches of Tonkla's abusive, alcoholic father.
In the present narrative, Korn encounters Samarn brutally tormenting Nan. With urgency, Korn pleads with Samarn to cease his actions and attempts to reason with Nan, promising her freedom and financial compensation if she reveals her contacts. He sternly warns Samarn against harming her, yet the brute responds by kicking Nan moments after Korn departs.
Elsewhere, Lukwa visits Den, revealing a haunting vision from her near-fatal cardiac arrest. She finds herself at an exhibition, the clock striking 4:00, accompanied by an unexpected guest—Great.
Korn, lost in bitter reminiscence of being rejected by Tonkla, finds solace in Great's companionship. Korn laments his perceived failures, while Great cautiously inquiries about his job, learning that one misstep could spell disaster. Korn becomes evasive, prompting Great to distract him with alcohol. Korn, deeply affectionate towards his brother, succumbs to his drunken state, allowing Great to access his phone and uncover Nan's location. Great promptly shares this with Tyme and races to her rescue.
Tyme, engrossed in an operation, only belatedly sees the message, arriving at the warehouse just after Great has infiltrated it. He discovers Samarn brutalizing Nan, who provokes him to the point of murder. Panicked, Great uses his time-warping ability to revert to four minutes prior, this time rushing in immediately and claiming Korn's authority to retrieve Nan. Samarn, bewildered, attempts to contact Korn while Great makes a desperate bid to flee with Nan. Realizing the deception, Samarn and his guards corner Great and Nan. However, Tyme arrives just in time, disarming two guards. Great joins the fray, and together they seize weapons from the fallen adversaries. Unable to shoot Great, a furious Samarn reluctantly lets them escape.
After delivering Nan to the hospital, Great halts in an isolated spot, ecstatically celebrating their daring escape. Tyme, amused, compares Great's visions to the powers of superheroes. They seek refuge in a hotel, where Great is still high on adrenaline. Tyme finds his excitement endearing as he attempts to tidy his disheveled hair, leading to a passionate kiss and an intimate encounter.
At the hospital, Dome is discharged, Nurse Bee handing him his prescriptions and medications. With a warm goodbye, he mentions his return home. His steps lead him to Tonkla's residence, where he calls out, addressing Tonkla as his brother. Tonkla, shocked by the voice yet unable to see anyone, stands puzzled.
The climactic revelation in the final scene of Episode 4 of 4Minutes reveals that the funeral Tonkla organized was for Dome, whose government name is Anawat Warindej. Their kinship is not just brotherly but also identifies Tonkla, Anuwat Warindej, as the prime suspect in the ongoing mystery.
