Three thieves rip off a shipment of used money being sent back to the US. As they are escaping the robbery (after having taken a hostage), they wind up on an island in a hotel with an apparently crazed manager and a building full of demented residents.
At a farmhouse, a large family cooks mountains of food for the next day's engagement party for Silvia and her city fiancé, Angelo. Her parents feud about infidelity; an aging salesman who rents a cottage from them arrives with a young French woman; in Bologna, Angelo's mother frets that her son is marrying beneath him; his sisters are less critical. Early the next morning, the four of them go by train to the farmhouse, joined by Angelo's married, unpregnant sister. The day-long dinner is riotous, couples display affection and impatience, children chase angels. Angelo's family stays the night, and his sister Linda has a visitor. A silver elephant makes the perfect gift.
A petty crook gallantly consoles wealthy widows and is doing all right in his chosen profession until he meets and falls in love with a lovely baroness, who knows all about get-rich-quick schemes.
