A trigger happy cop charges into a stakeout set up by an informant and forces Bumper Morgan into an all-out battle. Stolen whiskey, an arrogant coworker and a handgun shipment provide Bumper (George Kennedy) with a barrage of problems.

Bumper stirs up trouble among the hoodlums and hookers of his beat when he tries to steer a young girl into a safer life, while, off the job, he dates a glamorous career woman (played by Barbara Rhoades), whose world is very different from his.
