Photographer Jackson Riley is annoyed. He gets called to an unusual job where he's given few details, and the client doesn't seem to understand the time involved in taking large format photographs, which they specifically requested. Even worse, he almost misses the shuttle bus taking him back to his vehicle. But that's when his entire life changes. He barely escapes horrifying peril on the shuttle and races away in his car, only to rescue an enigmatic woman named Nadine who barely speaks to him. In doing so, he wonders what strange new terrors he's discovered. Seeking to uncover the answer to the mystery, he drives away from the city and hopes to outrun any danger while also keeping his new companion safe. Eventually, however, he is no longer sure that running for the rest of his life is enough. To end the threat, he thinks he may have to return to the starting point but wonders if Nadine is too traumatized to face it again. Facing the choice of what to do with the mysterious woman he supposedly rescued, he must decide if he will protect her at all costs or if he will put her at risk to save the last of humanity.
