So is it two divided by one which is suppose to mean?
This mostly Canadian creation, if you didn't know any backstory or plot hints, after watching for at least half the movie you would conclude it's about two very different, slightly dysfunctional, men on opposite sides of Earth living excessive self-achieving competitive lives. One taking Benzodiazepine (a sedative to help anxiety ridden sleep issues).
I actually missed the connection that one sleeps while the other is awake, but did sense that there was some connection between the two such that they were likely to meet - unless something horrible was destined.
Could have used more clarity and less jumping back 'n' forth.
