The Last Days (2013)

People start catching an extreme form of agoraphobia -- they’re scared of going outside, but the fear is well-placed because, if they go, they’ll die.

We follow Marc, a developer who's been trapped at his tech company with several dozen employees for months. He’s determined to get back to his girlfriend so, along with the corporate downsizer who happened to be onsite when the crisis came to a head, he ventures into the sewers to get across town. 

This doesn’t feel like anything new, but it’s done well and the ending is especially poignant.
