Yeong-ju is introduced as a girl with a cute look, a warm, innocent smile, and a knack for talking her way through most things. Yet behind that charm lies a woman who is currently in prison for fraud. When the evaluation board grants her parole, it comes with a moment of doubt and relief: she uses this second chance to attend her older sister’s wedding. The moment she is released, she hops aboard a train bound for Busan, carrying a small bundle of wooden ducks she crafted as a wedding gift.
On the train, Yeong-ju sits opposite a village pharmacist named Hee-cheol, who is on a personal mission to propose to his girlfriend with a family heirloom ring that once belonged to his late mother. The scene turns tense when a pickpocket steals the ring from Hee-cheol. Fearful that she might be blamed for the theft and risk losing her hard-won parole, Yeong-ju makes a swift decision to recover the ring for him. In the process, she ends up missing the train and leaving behind the bag that contained her handmade wedding gift.
Determined to recover her bag, Yeong-ju tracks Hee-cheol to his hometown, Yonggang Village. Once there, a tangle of misunderstandings unfolds: Hee-cheol’s family members mistake Yeong-ju for their future daughter-in-law because of the ring. Sensing an opportunity to retrieve her bag with minimal risk, she chooses to go along with the lie. In a perilous bluff, she even claims that Hee-cheol is the father of her unborn child. All the while, Hee-cheol returns home weighed down by the heartbreak of the broken proposal, only to discover that his fiancée’s fate now rests on a web of deception. The family’s belief that he abandoned his pregnant partner leaves him isolated and exiled from the household.
As the truth and the lie duel for dominance, the two leads navigate a complicated path that gradually shifts their perceptions of each other. Through the shifting dynamics of mistaken identity and fragile trust, Yeong-ju and Hee-cheol begin to see parts of themselves they hadn’t acknowledged before. The tension between honesty and convenience propels their conversations, and slowly, they start to understand one another beyond the surface. What begins as a precarious scheme begins to soften into genuine connection, and the distance between truth and emotion narrows.
In the end, the film centers on the tension between what is real and what is manufactured, and how two stubborn, wounded people might find a sincere path to each other when they allow truth to surface. Their evolving relationship unfolds against a backdrop of family expectations, past regrets, and the desire for a fresh start. What starts as farce, mistaken identities, and a heavy reliance on pretense slowly gives way to a more honest, hopeful understanding, as the pair discover that love can grow even in the midst of fragile lies. The story remains grounded in everyday choices and the quiet moments between characters, preserving a tone that is empathetic, reflective, and ultimately about choosing to trust each other when it matters most.
