They say we are what our fathers leave behind. The latest Tamil film John Doe revolves around fathers of all kinds — one who fed shame and toxicity to his child, one who failed to stand by his daughter, and one who looks after a childlike wife. Even when they are absent, or through that very absence, some of these fathers keep shaping their children’s lives.

Which is why, even though John Doe revolves around the mysterious murder of an eight-year-old boy, director Madhumita begins her story elsewhere — with another boy child in another period who grows up listening to his terrorising, toxic police officer father humiliate him daily. The child can’t eat as much as he wants to, can’t score anything less than first rank, and isn’t even allowed to cry at his mother’s funeral.

As fate would have it, Chandru (Arjun Das) becomes a police officer, a Kerala Police Sub-Inspector in Kadampuzha. He has achieved what his father said he couldn’t, and yet Chandru’s father (Badava Gopi is a great casting choice; his voice becomes a character), even posthumously, has his clutches firmly on his son’s psyche, constantly chiding and shaming him, especially when he feels low or makes mistakes. Credit to Madhumita for how John Doe becomes the story of Chandru proving his father wrong by becoming a good police officer.

It is also about figuring out who he is. He knows he isn’t the person the voice in his head keeps portraying him to be; if so, who is he? In fact, even the film’s title alludes to this. ‘John Doe’ — as a coroner explains — is a term used in American law enforcement to refer to an unidentified male body or patient (‘Jane Doe’ is for a female). By attempting to identify and seek justice for this young John Doe, who was killed by drowning in a lake in Kadampuzha, Chandru is also identifying who he himself is and seeking justice for the child in him who was slowly killed.

Simultaneously, we follow a new family arriving in Kurinjimedu, Tamil Nadu: Darshana (Srishti Y), a widow, her eight-year-old son Hriday (Nirav S), and teenage daughter Lakshmi, a.k.a. Lucky (Zaara Vineet Chandhokhe). One evening, Hriday goes missing, after which Inspector of Police A Rao (Sanchana Natarajan) begins a missing-person investigation. By initially showing the drowned corpse of a boy who resembles Hriday in Kadampuzha, Madhumita ensures that every additional shot of Hriday, a normal child who just wanted a dog in his new, spacious house, disturbs you. The rest of the film shuttles between Kurinjimedu and Kadampuzha, and these worlds collide when Chandru unearths disturbing details.

First and foremost, if you believe the sole worth of a whodunit or investigative thriller lies in how cleverly it executes its climactic twist or reveals the killer’s identity, John Doe may compel you to rethink. A genre fan would see the pre-intermission twist coming from afar, and the film hardly tries to hide its killer. Though it mostly gets its casting right, in a whodunit, when you see a familiar face amidst a group of non-actors, you tend to look closer, which spoils the fun. A more experienced genre filmmaker could have done it differently to drive home the fact that anyone can commit crimes.

Such predictability aside, John Doe would compel your attention and keep you hooked throughout its runtime. Madhumita excels in the little moments between the dramatic spikes in the narrative. The nuances and the sensitive writing are what you might take home with you. Watch how a couple takes the news of the death of their child. Their son had gone missing five years ago, and Madhumita tells you what the psyche of such parents would be like — they don’t scream and wail as you might expect; the mother, who had held on to hope, struggles far more than the father, who had long accepted grief. Similarly, you will see a child suffering from trauma wanting a family member to accompany him into a psychologist’s room — because, to him, the doctor too is a stranger, and he doesn’t wish to go anywhere alone with him after what has happened to him. Now, also see how sensibly the psychologist (Karthik Kumar) behaves, in contrast to the hot-blooded cops. We wish more filmmakers had this emotional aptitude.
