This is the story of Willard Stiles who is a social misfit taking care of his ill and fragile but verbally abusive mother Henrietta in a musty old mansion that is also home to a colony of rats. Willard then finds himself constantly humiliated in front of his co-workers and is eventually fired by his cruel and uncaring boss, Mr. Frank Martin, a vicious man whose professional interest in Willard extends to a personal financial one. When Willard becomes fascinated with the gaggle of rats living in his decrepit home, they become both his friends and his aggressors, as he wills them upon anyone who crosses his path. But one rat, Ben, isn't so amenable to Willard's orders, and a horrifying test of wills begins.
