I watched this film on one of those giant compilations of horror movies and it was totally nonsensical! The plot sounds pretty basic, but there is just so much that just makes no sense. Also, they seem to set up a showdown between two characters that never materializes on screen. I think it is Australian and is sort of a zombie film, but not really... https://www.imdb.com/title/tt0089002/?ref_=nv_sr_srsg_0
