The Alien Factor is a simple and cheap movie, but nonetheless entertaining and sympathetic. While the film lacks a serious dose of acting quality (most lines appear to be spoken without really convincing anybody), the creativity applied with simple means gives a very sympathetic touch to the end result.

The story takes the viewer along the developments in a small town when a couple of people are assaulted by alien beasts. At first, people believe a bear or something alike is responsible, but bit by bit the police and major learn there are alien powers at play
