The movie follows Baylor, a demoted Los Angeles Police Department officer who has been reassigned to a 911 call dispatch desk. From then on, we see the film sway to the rhythms of the erratic Baylor, complete with mood swings and emotional meltdowns. However "complex" the audience believes Baylor is, ultimately, he's still the main character and the only individual whose perspective defines the whole movie. It does a good job at throwing viewers off track as they follow the twists and turns in the plot. And indeed, the performance of a talented actor ensures the audience is glued to the screen even when the plot gets tangled.
