Just checked this out and I was really impressed - but warning if you are expecting DAWN OF THE DEAD or 28 DAYS LATER then you'll be dissapointed.
The film takes place in a radio station which has got reports of an outbreak - the suspense is built with their increasing knowledge of the situation. Its not an action movie but more about how people deal with WHAT IF..
Lots of it reminds me of THE SIGNEL and a bit of THE HAPPENING with regard to its pseudo-intellectual explaination but i went into this with no ideas about it and was very pleasantly suprised...
