Willard

Willard Stiles (Bruce Davison) is a meek social misfit who develops an affinity for rats after being ostracized by his co-workers and his domineering boss Al Martin (Ernest Borgnine). After Socrates, one of his rats, is killed by Al, Willard goes on a rampage using his rats to attack those who have been tormenting him. As Willard's relationship with the rats grows, so does their number, leading to a tragic confrontation with his tormentor.
