A group of three archæologists are on a dig when one of them uncovers a strange piece of jaw bone from a rodent that was larger than any other creature of its time. They then discover that — gasp, surprise! — the killer rodents are still alive to this day. (Don’t ask how. The given explanation degenerated from “being a stretch” to “totally ridiculous” in a matter of a few seconds.) When the party tries to capture one of the rodents alive, it of course attacks, along with a whole horde of other hand puppet cousin critters. (Think the killer bunny sequence from “Monty Python and the Holy Grail.”) Needless to say, lots of fake blood flows freely and everyone dies. I don’t know. If director Eric Fogel is hoping for a career directing generic slasher/horror flicks, then “Bite Radius” proves he can do that competently. Other than that, this is merely a run-of-the-mill low budget horror short.
