From NetFlix:

Six years after aliens invaded Earth, a security force maintains tenuous control in the Infected Zone straddling the U.S.-Mexican border. Andrew (Scoot McNairy), a photographer, is documenting this war-torn area when he’s interrupted by an unexpected rescue mission. Samantha (Whitney Able), daughter of a media mogul who just happens to be his boss, needs an escort home, and Andrew reluctantly takes on the job.

Only superficially is this a horror film. Rather it is more an independent film that is somewhat like a travelogue showing an American man and woman trying to get out of Mexico’s monster-infected region and back safely into the United States. Underlying the trip are his problems with his illigitimate son and her problems with her parents and her fiancee. Kids would be bored to death and if you do not like slow-paced films then you too can be bored to death. Yes, you get to see a monster or two, but it really doesn’t matter.

Probably the most impressive site was the gigantic Hadrian’s wall that has been constructed on the border between the U.S. and Mexico. For details about the many mistakes and the effort involved see the Wikipedia article.
