Domain (2017)

After a deadly virus wipes out most of humanity, the survivors are forced to wait alone in self-sustaining bunkers while the viral threat runs its course. Able to communicate through a networked video interface, the survivors wait for years and slowly become a motley family of sorts. But their fragile social ecosystem is shattered when, one by one, they start mysteriously disappearing from their bunkers.
