Corky Romano (Chris Kattan) is stunned when one day he receives a surprising call from his long-lost father, "Pops" (Peter Falk), an underworld crime lord. With his trial just two weeks away, Pops realizes that the one person who can turn the tables and steel the incriminating evidence, is Corky, who was banished from the "family" at a young age because he didn't fit in. Corky is very happy to help his Dad and soon he obtains a fake resume that gets him inside FBI. Under the guise of superagent Pissant, he tries to fake his way through one tough assignment after another while hunting for the incriminating proof of Dad's illegal activities.
