A Hard Day: The Cop, the Corpse, and the Coffin

The Korean title of Kim Seong-hun’s 2014 thriller translates as something close to Go Until the End, which is a better description of the film than the English one. A Hard Day sounds like a shrug. The picture is a machine for finding out how much worse a single night can get, and it keeps finding out for another ninety minutes after the point where any reasonable film would have run out of road.

It played the Directors’ Fortnight at Cannes in 2014 and it has been quietly colonising streaming menus ever since, mostly by word of mouth from people who put it on expecting a police thriller and found themselves laughing at something appalling. It is one of the most precisely engineered genre films Korea has made, and the engineering is worth taking apart, because the trick it pulls is much harder than it looks.

One bad night, then a worse morning

Detective Go Gun-su, played by Lee Sun-kyun, is having a comprehensively bad day before the film gives him a real problem. His mother has died. His marriage is over. His daughter is at the funeral home waiting for him. And Internal Affairs have chosen this week to turn over his station, where Gun-su and his colleagues have been running the sort of small-scale evidence-locker corruption that everybody knows about and nobody writes down.

He is driving to the funeral, and he has been drinking, and on a dark road he hits a man.

What Kim does next is the whole film in miniature. Gun-su does not go to pieces. He is a detective; he has spent his career watching other people make this exact decision badly, and he makes it with a professional’s clarity. He puts the body in the boot. And when the obvious problems with the boot present themselves — the police checkpoint, the neighbours, the eventual smell — he arrives at the only genuinely secure, guaranteed-to-be-buried, nobody-will-ever-open-it container available to a man attending his own mother’s funeral.

Then his phone rings, and a voice tells him it saw what he did.

Why it works: the escalation engine

Most thrillers are built on a mystery. A Hard Day is built on a schedule. The film’s mechanism is that every solution Gun-su devises is genuinely clever, works exactly as intended, and creates a new problem strictly larger than the one it solved. He is never stupid. This is the crucial design choice and the reason the film sustains: audiences forgive a lot, but they will not stay in a seat watching a man be an idiot for two hours. Gun-su is competent, resourceful and quick, and he is being defeated by arithmetic.

Kim’s second choice is to run the comedy and the dread through the same valve. There is a moment in the funeral-home sequence — an extended, near-silent stretch of the film in which Gun-su must get a corpse into a building full of his own relatives and colleagues, all of whom are there because of a different corpse — where the tension is unbearable and the situation is objectively hilarious, and Kim refuses to signal which one you are supposed to be feeling. No comic scoring. No cutaway to a raised eyebrow. He simply lets the horror of it be funny on its own terms, which is a far riskier way to play a scene than nudging the audience, and which is why the sequence has survived a decade of clips.

The third piece of engineering is the withholding of the blackmailer. For a long stretch the antagonist is a voice on a telephone that knows too much, and Kim keeps him off screen well past the point where a lesser film would have shown its hand. What makes this work is that the voice is not making threats. It is making demands, calmly, like a man arranging a delivery, and the mismatch between the register and the content does more damage than any amount of menace.

Lee Sun-kyun is superb, and his performance is the reason the tone holds. He plays Gun-su as a man operating at the absolute ceiling of his competence and just below the floor of his morality: sweating, calculating, lying fluently to people he loves, and — this is the detail that makes the character — occasionally catching sight of himself doing it. He is never allowed the comfort of not knowing what he is. Cho Jin-woong, when the film finally lets him into the frame, plays the opposite: a man entirely at ease.

The case against

The last act goes big, and the film pays for it. Kim’s instinct through the first two thirds is that the horror is domestic — a boot, a coffin, a phone, a daughter in the next room — and the finale trades all of that for machinery and open space and a scale of destruction that any competent action director could have delivered. The escalation engine has been running so precisely that when it finally cashes out in property damage it feels like a smaller idea, not a bigger one.

The corruption material is also thinner than the film pretends. Gun-su’s venality is established efficiently and then largely used as a plot lock — it is why he cannot go to his colleagues — rather than examined. Memories of Murder is the standard against which Korean films about bent policing get measured, and A Hard Day is not trying to reach it; it wants the institutional rot as a set of walls for the maze rather than as a subject. That is a legitimate choice and it does cost the film weight.

And the plotting requires a coincidence at the hinge — the specific reason the blackmailer knows what he knows — that is more convenient than the rest of the construction deserves. It goes past at speed. It does not survive a second viewing.

The real ancestor

Everyone reaches for the Coens, and Blood Simple is the correct reference for the structure: a small crime, a competent person, and a cascade of reasonable decisions that arrive somewhere unspeakable. The Coens worked out in 1984 that the engine of a crime film could be the labour of concealment — that the burying is more interesting than the killing — and every film since that makes an audience watch someone dig has been paying royalties.

The ancestor of the tone, though, is Hitchcock, and specifically The Trouble with Harry from 1955: a body in the countryside that a village keeps burying and un-burying, played entirely as drawing-room comedy. It flopped in America and Hitchcock remained fond of it, and it is the film that established the corpse as a comic object — an inconvenient piece of furniture rather than a moral fact. A Hard Day is Harry with the safety off. The gag is identical; Kim has simply attached consequences to it.

The Korean cousin is The Chaser, which shares this film’s conviction that a thriller should be exhausting in the legs — both are built on physical labour and both make institutional slowness the real villain — though Na Hong-jin is furious where Kim is amused. For a broader route into the territory, Korean genre cinema: ten to start with maps the essentials.

The verdict

A Hard Day is a small film that has aged into a modern standard, and it earns that on craft rather than ambition. Kim Seong-hun set himself an unglamorous problem — one man, one body, one night, no supernatural assistance — and solved it with a sequence of escalations so cleanly built that you can feel the gears. The funeral-home stretch is one of the great sustained sequences of 2010s genre cinema, funny and unbearable at the same time and confident enough not to tell you which. The finale over-reaches and the sociology is decoration. What remains is a black comedy about a competent man being slowly demolished by arithmetic, carried by a lead performance that never once asks you to like him. It streams widely, it runs under two hours, and it is the film to put on when someone claims they don’t enjoy thrillers any more.

Spoilers below

The blackmailer is a policeman. Park Chang-min, played by Cho Jin-woong, is not a witness who happened to be on the road; he is a senior officer, and the man Gun-su killed was his associate — a partner in a corruption arrangement that had gone wrong, carrying something Chang-min needs back. The body in the coffin is evidence in a crime that has nothing to do with the road.

This is what turns the film from a farce into a trap. Gun-su has hidden the corpse in the one place in Korea he cannot go back to — his mother’s grave, in a family plot, under a headstone, attended by relatives — and Chang-min needs it exhumed. The blackmail is not about money or silence. It is a retrieval job, and Gun-su has to become a grave robber at his own mother’s funeral to survive it. The film’s second half is Gun-su un-doing, at gunpoint, the single most inspired thing he did in the first half.

Chang-min is the film’s best joke and its darkest idea. He is a decorated officer, publicly respectable, and entirely untouchable, and he explains this to Gun-su with the patience of a manager walking a junior through the org chart: nobody will believe a drunk detective under Internal Affairs investigation over a senior colleague. The corruption Gun-su was worried about in reel one turns out to have been the amateur version.

The finale is where Kim spends the goodwill. It moves to a demolition site and becomes a physical confrontation between the two men, with a car and heavy plant machinery doing most of the arguing, and it resolves the film’s moral question by simply killing Chang-min. Gun-su survives. He does not get away clean — the film leaves him holding the evidence of his own crime and the knowledge of what he did with his mother’s coffin — but the last note is closer to relief than to judgement, and the film’s willingness to let a corrupt drunk who killed a man on a road walk out the other side is either its final joke or the failure of nerve I suspect it is. Kim never quite decides, and Go Until the End stops just short of the end it promised.
