When Sarah starts wandering the halls, she runs into a zombie. She would have been killed (which would have probably made a better, if much shorter, movie), but she is saved by Jay (Kris Tearse). He tells her that while she’s been passed out, there are zombies loose everywhere. He is still in the hospital because he’s looking for his brother. Sarah tells him that she wants to find her father as well. Jay tells her that the zombies don’t open doors and just pass by unless they hear something. This is an important thing to note because somehow they learn to open doors eventually. The logic holes are quite huge in this film. Anyway, Sarah and Jay stumble across Steve and he joins them in their search. So far none of these characters have many redeeming qualities. Eventually, they find three other survivors, none of which are characters that you will like. At this point, they decide that they need to get out of the hospital. Since according to the doctor they found the hospital is quarantined, they have to go to his office, gets his keys, and then unlock the basement door to sneak out that way.
Eventually some of the group does escape the hospital and it really feels like the movie should end there, but it just wasn’t long enough so they add on another 20 minutes of them running around in the countryside and then eventually into the city. There really is no purpose to any of this footage though, as the ending solves nothing and just ends in a very unsatisfying scene.
I am a huge fan of zombie movies and even with one like Bong of the Dead, there were still enjoyable parts. Unfortunately, we couldn’t find anything enjoyable in Zombie Undead. The zombies were generic and there was no real plot. Escaping from a hospital just doesn’t count as a real plot and, while I realize they were searching for family members, that might have counted had they ever done any real looking. If they had bothered tying the initial bombing into anything other than "Oh hey, there was a terrorist attack earlier, I wonder if that has anything to do with this?" then that might have made things feel more satisfying. Zombie Undead is a movie that I would recommend avoiding.
