Matt Smith, Natalie Dormer and Stanely Tucci star in this Rabies horror movie. A superstrain of rabies has decimated humanity. People hide in a nuclear silo from the infected. The Rabies is untreatable. Morgan (Smith and his bizarre US accent) is an asymptomatic carrier. He helps them search for Patient Zero. What does the infected language sound like? TPTB don't bother to tell us.
Why is the female scientist boffing the Rabies carrier Morgan? The dialogue is stupid. The infected don't lie and don't like music. An infected snarks at Morgan. The infected attack. Morgan's infected wife is alive but he is still shagging another woman. Patient Zero is revealed, sorta. This was not good or relentlessly cruel.
