A bunch of fairly unlikable hikers go camping in the woods but become victims of a bloodthirsty zombie/vampire creature. Turns out this creature is a victim of the Feral Virus, and everybody it attacks dies, then reanimates as another creature. So not a great deal of imagination has gone into the plot, but to be fair to most of us horror fans that's not a big deal. It is predictable and the acting varies in quality but it does deliver some decent gore.
In one scene a guy gets his ankle painfully stuck in a bear trap when one of the girls, the most annoying character , asks him "Are you OK?" Really!! I wasn't sure if this was either bad script writing or if it was just to make this girl look really dumb.
Feral is an OK time filler but nothing more.
