I ladri

A cargo ship from America arrives in Naples, Italy. As the dockworkers unload the cargo, a jam-jar rolls out of a packing case, and dockworker Vincenzo Scognamiglio picks it up, opens it, and finds it stuffed with coins. Slow-witted Vincenzo is puzzled by the discovery, but his shrew wife Maddalena realizes that the coins are part of a bigger consignment being smuggled into the country. After reading a newspaper article about Joe Castagnato, an American counterfeiter and thief who has recently arrived in Naples, Maddalena puts two and two together. Accompanied by her buffoonish family, she visits Castagnato and insists that he cut them in on the score. Meanwhile, garrulous, vain Police Commissioner Di Savio of Naples is on the case, and and an odd-looking agent from the American FBI is monitoring his investigation..
