A mild-mannered introvert lives with his mom in an old house. He works at a firm that his dad help start, but his boss does not like him, and constantly picks on him. One day, he makes friends with a rat in his basement, and soon, has collected a small army of rats, which willingly obey him. When his boss gives him a particularly hard time, he decides it is time his rat army lent a hand... Best viewed as an over-the-top horror movie rather than straight horror.
