Mystery unfolds as a group of individuals are confronted by undead forces outside of an abandoned factory. Rewinding their encounters only one day before, the major players of the group go about their business as usual. As they all unwittingly gather up at a local hotel for personal reasons, an unexplanatory virus breaks out that turns people into blood-lusting beings. Consequentially, the characters are stuck at the penthouse suite they were having lunch in. As time passes, the group decides to make a run for survival before battling down to the parking lot. Through struggle, betrayal, and loss, the remaining individuals desperately make it out of the hotel alive and arrive at the factory where we first meet them. While this is only a temporary haven, they are tested once again by new circumstances. Who amongst them will survive?
