“Affection is the greatest obstacle on the path to success” according to the villain at the centre of Cheng Wei-Hao’s philosophical mystery, The Soul (緝魂, Jī Hún). Adapted from a science-fiction novel by Jiang Bo, Cheng’s near future tale has a series of questions to ask about legacy, family, love, and repression as its earnest investigator tries to come to terms with his oncoming end while living with treatment resistant cancer and trying to decide what is the best way to support his wife and unborn child in his impending absence. 

In 2032, police are called to the palatial estate of a local tycoon only to find him brutally murdered. Perhaps there’s nothing so shocking about that, powerful men have enemies, yet the strange thing is that Wang (Samuel Ku) was already dying of brain cancer and had a very short time left to live so there would seem to be little advantage in bumping him off early. The prime suspect is his disgruntled son Tien-yu (Erek Lin) who was seen leaving the mansion in a hurry and is known to bear a grudge against his father over his mother’s death while Wang’s much younger second wife Li Yen (Sun Anke) also identifies him as the killer. But there are definitely a few things which don’t add up here. Why is Wang’s business partner Wan named as his second choice as heir after Li Yen despite the rumours he had been having an affair with first wife Su-chen (Baijia Zhang), why are there security cameras in Li Yen’s bedroom, and why would a man with so little time left to live opt for an arranged marriage to an orphaned 20-year-old woman from one of the orphanages his philanthropic organisation supports?

Those are all questions which immediately present themselves to veteran investigator Liang (Chang Chen) whose own wife Pau (Janine Chang Chun-ning), also a policewoman, is pregnant with their child while he has just learnt that his cancer has resisted all treatment and may in fact be incurable. Deciding his remaining time may be best spent providing what he can for his family he asks his boss for his job back and specifically to be put on the Wang case, immediately homing in on the company’s radical new treatment for cancer through transplanting rejuvenated neurons directly into the brain. He begins to wonder what comes with it if you begin implanting neurons that belong to someone else but gets no reply from Wan in the middle of his sales pitch. 

Hinted at in the Chinese title the question that arises is that of the connection between soul and flesh and whether it becomes possible to achieve a kind of immortality through colonising brains in healthy bodies, an idea which might of course prove appealing to Liang if he were not so innately incorruptible. Then again as his wife says, perhaps it’s easier to die. It’s the ones left behind who have it hardest, suddenly left to deal with everything on their own. That might be why she finds herself tempted by their rather obvious conflict of interest in compromising her integrity to buy her husband a few more days while he wonders what the point of such a sacrifice might be.

Yet what we discover in the unhappy saga of the Wangs is both a megalomaniacal obsession with control that extends beyond one’s own lifetime and a tragic love story born of internalised shame that led to a lifetime of repression and unhappiness in the inability to be one’s authentic self. Liang describes the RNA treatment as an expression of the living’s obsession with the dead, while others describe it as “modern necromancy” oddly echoing the black magic which Su-chen, herself a neuroscientist, and her son had apparently been practicing in their intense resentment of Wang. Pau insists she’d rather believe a soul exists no matter in what form, but if you make division of yourself you may also face an unexpected existential threat born of your own internal conflicts and mutual desire for survival. A slow burn mystery, Cheng’s eerie drama has its share of hokum but nevertheless asks some pertinent questions about the nature of humanity in an increasingly technological age, what it is we leave behind and how it is we move forward (or not) with the process of letting go even as its ironic final moments provide a kind of justice emotional and literal in restoration of a family.
