The film introduces us to Ethan, played by Douglas Smith, a young man suffering from amnesia, memory lapses and sudden loss of consciousness.
We find ourselves in a semi-rural, half-apocalyptic setting after the abrupt incursion of a plant-borne virus.
After one of his lapses Ethan meets Mae, played by Carrie-Anne Moss. We are also briefly introduced to the character played by Frank Grillo, the bad guy, the relentless pursuer.
As the film progresses, Ethan leaves Mae to go in search of his girlfriend, Emma, but the search ends with little success.

In flashbacks, director Lowell Dean, also a screenwriter, tells us what happened to Ethan and Emma in their flight to escape the virus and why Ethan now finds himself in this situation.
It is a well-written film, which knows how to dose the information to generate suspense. The plot presents many unknowns that are revealed little by little, offering a story that avoids the typical conventions of zombie films.
You will have survivors, humans who are more dangerous than the monsters themselves, but the plot knows how to use this context only as a scenario to develop a story that grabs you by the mystery of what is really happening.
Technically decent, this is a post-apocalyptic romantic drama with some social criticism. The script is certainly rounded, but not unexpectedly so.
The film is watchable because the performances are good and the photography is good, but little else.
It also includes some environmental criticism, of course, pointing out details such as the fact that we have already fought against several viruses, but that one has come along that will really establish order on the planet.
This is one of those films that I recommend watching without having any idea about anything, or reading any commentary, one of those films that if it had been directed by someone well-known, it would be on everyone's lips, for better or for worse.
