Good-natured veterinarian Corky Romano is stunned when he receives a call from his long-lost father, "Pops" an underworld crime lord who has been indicted. With his trial just two weeks away, it looks as if the Mafia kingpin is finally going down. However, he still has one hope. 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, who was banished from the family at a young age for not fitting in. Corky is only too happy to help his newly rediscovered relations, and so his brothers intimidate a computer hacker into creating a fake resume to get Corky into the FBI. But the hacker panics and goes overboard, making Corky appear to be a super agent, a reputation to which he is forced live up. Under the guise of agent Pissant, he stumbles into the hallowed halls of justice and tries to fake his way through tough assignments while hunting for the elusive incriminating proof of dear old dad's illegal operations.
