A social misfit, Willard (Bruce Davison), is made fun of by his co-workers and squeezed out of the company started by his deceased father by his boss. His only friends are a couple of rats he raised at home, Ben and Socrates (and their increasing number of friends). However, when Socrates is killed at work, Willard goes on a rampage, using his rats to attack those who have been tormenting him. Also with Ernest Borgnine, Elsa Lanchester and Sondra Locke.
On July 8, 2012, Ernest Borgnine died of renal failure at the Cedars-Sinai Medical Center in Los Angeles, CA with his wife and children at his side. He was 95.
