There is a chemical released to create mutants, then they are nuked, but there is no real signs of that. A group of survivors are hunkered together when the "new guy" shows up. In this case it is Shinji (Andre McCoy) a quiet special ops type who wears his sunglasses at night. There is some poorly developed drama within the group made worse because the acting was bad. Perhaps the worse in the group is Kat (Isabella Marie Brown-Quigley) who believes everyone hates her because she is just 18, and not because of her acting.
The script gives out information and then brings it together in the most boring way possible. Most of the film was done in a warehouse. We do get a long lecture on how rat poison works. The mutants are walking dead, but are killed by normal methods.
