Peccato che sia una canaglia

How did Lina Stroppiani (Sophia Loren) and Paolo (Marcello Mastroianni) meet? The buxom blonde stole Paolo's cab -- literally. The taxi driver's efforts to bring her to justice lead nowhere. Enraged and smitten, Paolo investigates, and discovers that Lina comes from a long line of con artists, including her respectable-looking father, Vittorio (Vittorio De Sica). For Paolo, the only way to reform Lina without becoming one of her victims seems clear: marry her and join the family.
