When Florida's two stupidest cons, the Salchek brothers, escape from prison and steal a baseball worth millions from infamous mob boss Charlie Lucre, Karen turns to their mother, a hapless waitress living in a trailer park, for clues on how to find them before Lucre's hitmen do.

When a suave con artist who bilks women out of their fortunes manages to slip away from Karen the minute he's off the plane, she's humiliated but determined to bring him in, despite the fact the FBI has ordered her off the case. Meanwhile, a former mob accountant suddenly returns from hiding in the witness protection program, putting his — and Karen's — life in jeopardy; and Marshall is unhappy to find that Karen's old boyfriend, a married FBI agent, is back on the scene.
