King of the Ants

Sean Crawley (Chris L. McKenna), a young man struggling to make ends meet in suburban Los Angeles, is hired by Duke Wayne to kill Eric Gatley, an accountant investigating shady real estate developer Ray Matthews' company. After breaking into Gatley's house and beating him to death, Sean discovers that he has been double-crossed and that Matthews never intended to pay him for the hit. As revenge, Sean tortures Matthews' men, eventually killing Matthews himself and escaping with the help of his friend George. He then befriends Susan Gatley, Eric's wife, but after she recognizes him as her husband's killer, she attacks him and he accidentally kills her in self-defense, leading to a final campaign of revenge against Matthews.
