The Russo family and friends are headed to Tuscany, Italy, to meet their long lost relatives... but when Alex tries to prove she's more than a seemingly carefree young Wizard, she inadvertently conjures a spell that creates a Good Alex and an Evil Alex. When Evil Alex gets roped into a charming young wizard's foreboding plan to take over the world, Good Alex must find a way to save her family and humankind, which leads to a monumental battle between the two versions of herself - all atop the Tower of Pisa.
