The Last Kind (2014)

A new deadly mutagen virus is introduced to the public on the busiest day of the year, Black Friday, creating the fastest spreading outbreak known to mankind. The deceased and infected soon come back to life as hosts for the R91X virus to spread itself. During the day, the resurrected are slow mindless hosts, who soon exhibit aggressive behaviors. Though, at night, they will mutate into quicker, intelligent, muscular monsters. The human race begins to dwindle as the infected take over. Now, survivors must join together to stay alive in a post-apocalyptic world.
