Piero Spazin (George Ardisson) is a con artist who meets his friend Luigi Beton (Daniele Vargas), a fraudster, and the two get engaged in a new fraud scheme, also attempting to trick each other at the same time. Angela (Staller), a supposedly naive employee of Piero's fiancee Augusta (Anna Maria Pescatori) becomes accidentally involved in their plan and agrees to accompany them on their journey. However, joining of Susy (Orchidea De Santis), another con artist to the group after meeting Luigi's son Rodolfo (Graziano Chiaro) makes things even more complicated.
