Good-natured veterinarian Corky Romano, long banished from his underworld crime family for not fitting in, is stunned when he receives a call from his crime lord father. Pops realizes that the one person who can turn the tables and infiltrate the FBI undetected--and abscond with the evidence against him--is Corky. Under the guise of Agent Pissant, Corky stumbles into the hallowed halls of justice and tries to fake his way through one tough assignment after another while hunting for the elusive incriminating proof of dear ol' dad's illegal activities.
