Na Doo-su, Lee Seung-hyeon, nicknamed Yalkae (a cheeky, cocky person), is a second-year student at a Christian missionary high school who often acts like a troublemaker because of his rocky academic record. His everyday routine is upended when a new teacher arrives: Baek Sang-do, Kim Jung-hoon, a mentor who was once the father of Na Doo-su’s apprentice.

Na Doo-su, while running errands for Baek, finds his heart drawn to Insook, a convenient-store clerk and a Moran Girls High School student. In his bid to connect with her, he joins a biking club, hoping it will bring them closer together. Meanwhile, the Na family schemes to marry off Na Doo-su’s older sister, Na Du-ju, to Baek. Baek works as a private tutor for Na Doo-su, and through those tutoring sessions, Na Du-ju starts talking with him, adding another layer to the evolving dynamics.

Baek encourages Insook to keep a respectful distance from Du-su in the name of his academic improvement, setting up a quiet tension between affection and obligation. The tension thickens when Du-su pulls a prank on Hocheol, a diligent though poor student, by painting his glasses red, which leads to the glasses breaking. Baek’s anger flares, and he contemplates removing Du-su from the school, but a later teachers’ meeting ends with Baek pleading for forgiveness and saving Du-su from expulsion.

The following day, Hocheol is absent from class. Du-su goes to his home and finds Hocheol with a wounded leg, the result of a bike ride gone wrong due to poor eyesight. Feeling guilty, Du-su apologizes, and Hocheol responds with a powerful message about a brighter future. Inspired, Du-su decides to help by delivering milk to earn money, and as he does, his own grades begin to improve.

Du-su learns from Hocheol’s neighbor that the condition of Hocheol’s leg has worsened, and he makes a trip to the hospital to gift him a pair of new glasses. While delivering milk, Du-su himself is hurt in a traffic accident, yet his concern for Hocheol remains unwavering. The story also highlights the caring influence of Principal Richard Hudson and the support of Du-su’s family and friends.

In the end, the film resolves with a hopeful, celebratory note: Du-su and Insook’s relationship is officially acknowledged, and Baek’s betrothal to Na Du-ju is celebrated, bringing a warm sense of closure to their intertwined lives.

Yalkae, a Joker in High School Spoiler-Free Summary

Discover the spoiler-free summary of Yalkae, a Joker in High School (1976). Get a concise overview without any spoilers.


In a modest Christian missionary high school, the rhythm of daily lessons is punctuated by the restless energy of its students, their lives humming between strict expectations and the yearning for moments that feel genuinely theirs. The campus is a micro‑cosm where teachers try to steer futures, while families quietly orchestrate matches and ambitions beneath the school’s orderly façade. A light‑hearted yet affectionate atmosphere pervades, hinting at the turbulence that adolescence inevitably brings.

At the heart of this world is Na Doo‑su, known to his peers as Yalkae—a second‑year student whose reputation for pranks and a carefree attitude makes him both a legend and a headache for faculty. Beside him stands his loyal accomplice Yong Ho, a kindred spirit who shares the same disdain for the grind of textbooks. Their mischief is less about malice and more about carving out an identity in a place that seems to value conformity over curiosity, setting the stage for a constant dance between rebellion and responsibility.

The arrival of a new teacher, Baek Sang‑do, shakes the status quo. Once a mentor to Doo‑su’s older sibling, he brings a different blend of stern guidance and unexpected empathy, challenging the pranksters to reconsider the impact of their actions. Meanwhile, Doo‑su’s growing affection for Insook, a convenience‑store clerk who balances her own studies at a neighboring girls’ school, adds a tender thread to his otherwise chaotic tapestry. His older sister Na Du‑ju navigates her own pressures, hinting at family dynamics that intertwine with the school’s social currents.

Amid the laughter and occasional scoldings, the presence of diligent classmates like Hocheol offers a quiet contrast, embodying the academic aspirations that linger in every hallway. The principal, Richard Hudson, and the wider community round out a setting where humor, hope, and a quest for self‑discovery pulse beneath the surface, inviting viewers to wonder how youthful defiance might evolve when faced with genuine guidance and unforeseen connections.
