Mobius 不眠日(2025) A Recommendation

As a longtime fan of any kind of screenplay featuring temporal devices I was intrigued to see this pop up on my Netflix feed. What got me even more psyched was the image of Bai Jingting as the lead in his latest time loop drama after Reset. Better still is having him play a competent cop, Ding Qi, on this occasion. A’Qi has the ability to perceive time loops on seemingly random days where he is given five opportunities to get it right. It’s a handy ability for a dedicated detective trying to crack knotty cases and save lives. In a series of flashbacks early on we see how he got his start as a time looper but like Phil Connors of Groundhog Day fame, living it up in self-indulgence loses its charm rather quickly. After an epiphanous moment, he embarks on a more meaningful trajectory by joining the police to better utilize his “ability”. Episode 1 is an excellent introduction to the show’s protagonist, his motivations and the implications of the narrative device for the characters and the plot. Although Bai Jingting brings his A game to everything he does, Bai Jingting playing cop and action hero is my favourite thing in his ever expanding resume. For fans of police procedurals, it is a boon on so many levels.

Mobius of course is a reference to the mobius strip which the Britannica defines as “a geometric surface with one side and one boundary… it is formed by giving a half-twist to a rectangular strip and joining the ends.” That is to say, a loop with a bit of a twist. It was referenced in The Avengers: Endgame as a means of understanding how the past can be revisited and even altered while doing no or little damage. Something similar takes place here. Moreover it’s a case of “5 strikes and you’re out” so it gives Ding Qi the opportunity to investigate various possibilities and dig up the facts in a race against the clock. There is a downside to the ability of course. He can’t tell anyone about why he knows what he knows. In fact to his greatest frustration, he has to hold back from revealing key information which could expedite matters. The Chinese title 不眠日 means “sleepless day” which is what happens when Ding Qi is in a loop day frantically pulling out all the stops to solve crimes.

The world inhabited by Ding Qi and his colleagues appears to be a hodge podge of Hong Kong, Macau and the mainland. Even the action sequences are reminiscent of John Woo’s films. There’s plenty of code-switching from Mandarin to Cantonese which means that I really have to pay attention to the subs. At the centre of the metropolis that is Hua’ao, is the biotech giant developing gene-based therapy, Moma. Two of the company’s executives have died within a space of a month and on “loop days”. A’Qi quickly smells foul play. A mysterious figure knowns as “Squid” emerges hurling unhinged threats against the company’s CEO Mo Yuanzhi (Song Yang). Also connected to Moma is An Lan (Janice Man), a biomedical researcher and someone he has feelings for.

A’Qi enters the fray as a glorified bodyguard for Mo Yuanzhi at the behest of Tang Xin (daughter of one of the deceased men) but also concern for An Lan’s safety. What ensues is a series of red-herrings, rabbit trails and the bloody debris left from the complete collapse of medical ethics.

(Next paragraph could be spoilery)

While medical and research ethics come under the microscope here, beneath the cat and mouse game, underneath it all is about humanity’s continuing search to defeat mortality by any means possible. Gene therapy is the latest in a long tradition of pursuing the fountain of youth or the elixir to immortality. Part of it comes from an impulse to cheat death and even to hold on to the people around us. Satan is reported to have said in the book of Job “Skin for skin! All that a man has he will give for his life”; the other part of it is a motivation to attain something akin to the power of the divine. Alas time and tide waits for no man. Unless you’re a time looper.

Beginning with Bai Jingting, the actors are well cast in their respective roles. Bai Jingting proves himself not just to be a versatile actor but a smart one with a flair for comedy — nailing the character in every scene with timely perfection. Also superb is Song Yang who brings nuance and gravitas to the complex character of Mo Yuanzhi. Much credit must also be given to the director(s) who not only has assembled a great team of people to tell this story but also for the production values. The drama also boasts some really spectacular action set pieces not commonly seen in recent days. It would also be remiss of me not to mention the tight script which includes the careful plotting and better-than-usual characterization. All that aside, the entire show is another example of why all C dramas would be far better off being under 20 episodes.

It’s a fun watch particularly because I don’t try to think too much about the time mechanics and just allow myself to get lost in the crime solving aspect of the plot.
