Sean Crawley (Chris McKenna) is a part-time house painter who has stumbled on the dream job of a lifetime, when beer-guzzling electrician Duke Wayne (George Wendt) introduces him to the owner of a construction company, Ray Mathews (Daniel Baldwin). Ray pays Sean five hundred dollars a week to tail a pesky accountant from City Hall who has been threatening to expose his practice of bribing city building inspectors. All is fine until Ray drunkenly tells Sean that he'll pay him an extra thirteen thousand dollars to dispose of the accountant. To everyone's surprise, Sean does it! Problem is, Ray has no intention of paying him the money. To make matters worse, Duke informs him that if he talks, they'll crush him like an ant. What both Ray and Duke are about to discover is that Sean isn't any ordinary ant.
