Split into four timelines, the story starts with a naked body found in an alley in the year 2023 by the MOST politically correct cop ever, a Muslim female who wears a veil and who's probably gay... Not only that but she's a single mother and has a loving family composed of her aging father and cute kiddo. Note that the family background is given only for her timeline, to show how maternal and loving she is.
The second timeline in the year 1941 is about a shady but discriminated Jewish cop who finds the same naked body in the same alley.
The third takes place in the year 1890 and the cop finds the same body surrounded by a whiff of - at the time illicit - gay cavorting.
The fourth is a stuck-on cliffhanger ending, taking place in the year 2053.
In the third timeline, there's the cliche introduction of a mysterious character, seen on a reflection in a photo. The autopsy doctor seems so terrified (why?) that he doesn't even want to mention the guy. Why can't they just say that the guy is someone rich and well-connected who should be left alone instead of hinting at fake mysteries? Because, who else could that guy be, other than somebody rich and well-connected?
In the first timeline, there's the even more annoying cliche of the "mother syndrome". Since the cop is female and we're shown how maternal she is, she must think she's responsible for the death of the Asian suspect, a perfect stranger who put himself in jeopardy and refused to give up. Responsible how? And why promise the sister she was going to protect him when as a cop she should know the situation was bound to slip out of control? Dumb and cliche, but after all, these are the tropes of the production. No matter in which era the story takes place, they all develop in the same way, with the same good (ethnic, female, gay) and bad characters (white males).
