Ah Boys to Men 4 (2017) – Full Plot Summary & Ending Explained

Read the complete plot breakdown of Ah Boys to Men 4 (2017), including all key story events, major twists, and the ending explained in detail. Discover what really happened—and what it all means.

Ken Chow [Joshua Tan] is a wealthy, pampered teenager who uses a war-based role-playing game as a shield against the real world, especially the looming duty of NS. He dreams of studying abroad with his girlfriend Amy, but those plans are halted when compulsory military service looms. After a tense confrontation with Amy about his childish behavior, Ken’s frustration erupts in a moment of reckless bravado that lands him in trouble with the law, setting a tone of stubborn defiance that threads through the rest of the story. As his parents brace for the disruption NS will bring, the family tries to keep his spirits up while he clings to the fantasy that he can dodge what awaits him. Ken [Joshua Tan] is forced to confront the reality that the discipline of NS will demand more than bravado and clever excuses.

Once enrolled, Ken and a cohort of new recruits are assigned to Ninja Company, Platon 2, Section 2, and are immediately introduced to their Platoon Sergeant [Tosh Zhang], a figure who will test their limits and shape their early impressions of military life. Among the batch, the recruits form quick, memorable bonds: [Lobang] (Wang Wei Liang) is a charismatic, gregarious presence who can smooth over rough moments with humor; [Aloysius Jin] (Maxi Lim Jun Liang) stands out for his education and his own high ambitions to become an army officer, bringing a calm, analytical perspective to chaotic training sessions; and [I.P. Man] (Noah Yap) is a somewhat anxious soul who frets about keeping his girlfriend Mayoki, who isn’t sure whether his service can coexist with their relationship. It’s a rough baptism by fire as they stumble through the basic drills, missteps during workouts, and the heat of long days that push他们 to their physical and mental limits. The group also includes other tight-knit members like [CPL Handsome] (Jaspers Lai) and [CPL Tan Keng Long] (Ryan Lian), who bring their own quirks to the platoon’s dynamic, hinting at the humor and camaraderie that will buoy them through tougher moments.

As the weeks pass, the new recruits begin to settle into a rhythm, and the routine of training becomes a mirror for the pressures that each man carries. They are not just learning to march and fire their weapons; they are learning to test boundaries, endure discomfort, and cope with fear in a system that demands obedience and resilience. The platoon’s hierarchical world is rendered with quiet detail—the orderly chaos of barracks life, the laughter that erupts after a failed drill, and the shared meals that become small rituals of solidarity. For Ken, the line between a pretend battlefield and real consequences remains blurred, even as the men form a fragile bridge of trust with one another under the gaze of their leaders.

Two weeks into training, the recruits finally earn their first “book out” and return home for a respite. Ken’s family throws a lavish party to celebrate, a moment meant to satisfy the fantasy of normalcy he longs for. Yet the celebration collapses when Ken discovers a photo of Amy with another man, a revelation that cuts deep and shatters the fragile equilibrium of his NS fantasy. The sting of betrayal feeds into a broader fear: that NS will strip away his control, and that love and security will slip away just when he needs them most. In a bid to prove himself and reclaim his standing, Ken hatches a desperate plan to skip out on Pulau Tekong, convinced that breaking away will somehow restore his autonomy and win back Amy’s affection. The plan, born of heartbreak and stubborn pride, nudges him toward dangerous choices that threaten not only his future but the well-being of those who care about him.

During a grueling training exercise in punishing heat, Ken makes a perilous move by deliberately limiting his water intake, hoping the resulting heat injury will force his return home for medical reasons. He even tries to sleep under a ceiling fan after cooling himself with water, thinking this will speed up his return to a world where he can control outcomes. The gambit backfires in spectacular fashion: his condition deteriorates rapidly, and he collapses in the midst of training. News of his collapse jolts the company into action, and his father receives an urgent call as Ken is rushed to a hospital. The shock of seeing his son in danger—combined with the family’s own mounting stress—helps trigger a severe stroke in Ken’s father, who is driving to the hospital and involved in a serious car crash while trying to reach his boy. The incident binds the family’s fate to Ken’s missteps in a way that makes the stakes painfully concrete.

Ken awakens to a hospital light and the quiet voices of his sisters, surrounded by the gravity of what his actions have set in motion. He realizes that his reckless behavior has caused great trouble for many people, including those who love him the most. The weight of responsibility lands squarely on his shoulders as he confronts the consequences of attempting to bend reality to fit a wishful dream. This moment of clarity becomes a turning point: Ken accepts that returning to training is not a punishment, but a test of character and commitment to those who depend on him. The narrative sustains this strain as he finds a new measure of resolve, preparing to face the rigorous path ahead rather than retreat into a fantasy.

From this point, the story threads toward a future that remains unwritten. The film ends at a moment of decision, with Ken still in training, the door left open for the next chapter of his journey. The closing images suggest that his path will be shaped by how well he balances self-preservation with duty, how he rebuilds trust with Amy, and how he navigates the complex bonds formed in the crucible of NS. What is clear is that the experience has already begun reshaping him, and the next segment of his life will demand even greater courage, discipline, and honesty.

In this portrait of adolescence pressed up against national service, the film quietly asks how far someone will go to protect a fragile sense of control, and what happens when the cost of that control collides with the responsibilities that come with growing up. It’s a spare, grounded exploration of fear, loyalty, and the stubborn hope that change, even when painful, can lead to a stronger sense of self.
