An amazing movie about a group of friends quarantined as they have been exposed to a virus which kills any who got it. Not only is this a great foreshadowing of the situation we are in now (since this was made before the pandemic), it also leads to a great who got it story and what would you do if you were trapped in a house with people who might have a virus that can kill you. Now put a mysterious murder in the mix and you have two killers in the house that is out to kill our people and make you wonder who will survive. Great job!
