After his auto-parts tycoon father dies, the overweight, underachieving son teams up with a snide accountant to try and save the family business.

After his beloved father (Brian Dennehy) dies, dimwitted Tommy Callahan (Chris Farley) inherits a near-bankrupt automobile parts factory in Sandusky, Ohio.

His brand new stepmother, Beverly (Bo Derek), wants to cash out and close, but Tommy's sentimental attachment to his father's employees spurs him to make one last-ditch effort to find someone who will buy their products. With his father's tightly wound assistant, Richard (David Spade), in tow, Tommy hits the road to scare up some new clients.
