After the success of CHRISTMAS AT ALL COSTS, the Delle Fave family leaves for a new adventure in Menorca. The intent is to protect the grandmother (and her rich inheritance) from the clutches of the slimy Nunzio, who has seduced the elderly woman and plans to marry her, taking her with him to South America and, probably, make her disappear into some hidden ravine of the Amazon River. Anna drags her husband and children into a crazy plan to save her mother: to kill her future husband a few days before the wedding..! Between family quarrels, old disagreements and near tragedies, the improvised killers will discover once again that the true treasure is being a family.
