A man in the federal witness protection program is killed in a hit-and-run accident. The FBI believes the Mob did it. Detective Patrick Delaney, engaged to Emily Peterson, runner-up in the Alice in Dairyland Beauty Contest, isn't so sure. A corrupt coach and a song-and-dance man wannabe from LA team up to undo a blackmailer. Their nincompoopery awakens a sleeper cell of bioterrorists; but not to worry. Detective Delaney and Professor Myron Willgrubs, with help from a mean Holstein bull, team up to catch the bad guys and solve the hit-and-run mystery.
