There is no cure for the zombie virus, but there is an injection to stop someone from fully turning into a flesh eating monster. Only problems the infected must be given the first injection within 36 hours of being infected, and the infected person must take a lifetime of shots so they don't turn, of course if they don't take their shots then they turn into a zombie. The movie follows Kate, a doctor who works with the infected, making sure they get their initial shot and they don't turn. Her job is a tough one, since not only does she help people not turn she has to tell their families how to care for them. No one wants to be infected and there are rumors of a lack of the serum is coming. People begin to panic.
Kate has a secret of her own, and she needs the serum, otherwise she will lose everything. After an incident at her hospital in which all of her infected patients are killed she runs with her husband, Alex. Fighting to keep things together, Kate and Alex run with another couple. The world suddenly falls into chaos as the serum is stolen and people become desperate for help, murdering those they can and stealing what they need, no matter who it hurts. Kate and Alex end up having to make a hard choice, and in the end everything changes.
I actually enjoyed this movie because the premise was a new one, a zombie injection that could stop the zombie virus from taking a person over, not something that I have read or seen in many books or movies. At times there was a little too much drama and the movie was a little too slow at certain points. One of the main issues for me was the beginning of the movie and the end, I really didn't care what happened to Kate as a child and I wanted to learn a little more about current relationships rather than past. If you enjoy zombie movies this is one you should watch because it is different, and anything that gives a new twist to an old genre is an interesting find.
