Bumbling insurance fraud investigator Frank McKlusky (Dave Sheridan) goes undercover on a case and can't get anything right. One needn't look further than Frank's family to learn the root of his problems -- Dolly Parton plays his blowsy, over-the-top mom, and Randy Quaid is his comatose father. The hilarious supporting cast includes Enrico Colantoni, Kevin Pollak, Orson Bean and Andy Richter.
