Dead Rising: Watchtower (2015)

Reporter Chase and his camerawoman are inside the quarantine zone trying to get the scoop on the latest zombie outbreak. The government is dispensing Zombrex to those who are infected. But something goes wrong and people start to turn.

Everyone starts running for their lives, and Chase gets separated from his cameraperson.  As more people start to turn, Chase has to figure out how to get to the edge of the quarantine zone where the military control the exit.

Unknown to the survivors, the military have been told to shut the gate and not let anyone leave. There is fear of the virus spreading outside the quarantine  zone.  Even those who appear to be fine are left inside to fend for themselves.

Chase teams up with two survivors in a bid to escape.. But along with zombies, there is a gang of bikers who are not going to help anyone but themselves - and they are pretty excited about looting and killing.

Nothing special or new about this one.
