The final leg of Alex's journey reaches a fitting crescendo in the secret south, a region that Alex knows little about. Puglia, one of the most rural regions, welcomes Alex first with a tour of its curious beehive shaped trulli and a wine with a difference. Next, the majestic Monte Pollino National Park is an unexpected delight, before her adventure concludes in the unique city of Matera. Here, Alex tours the atmospheric cave dwellings, some of the oldest settlements in Europe, before taking in the extraordinary annual festa, a carnival with a twist.

On an exclusive tour of Nestle's Perugina factory, we see the making of the Crunch Bar. Later, we delve into the aristocratic archives of a relative newcomer, the After Eight Mint. There are chocolate hearts and brains made for the Science Museum, a life-size baby bison fit for a lord, and a trip to the biggest chocolate festival in the world.

Baz scrubs up a tired old bathroom and transforms an unused space into every teenage girl's dream. Miguel adds a taste of home to a classic custard.

The Campania region is the setting for the penultimate part of Alex's journey. Beginning in Naples, she will immerse herself in the chaos of the city, feel the fear of living in the shadow of Vesuvius, and learn about its hugely superstitious folk. Following the trail of the Grand Tour, Alex heads to the Amalfi coast, the setting for a memorable part of her honeymoon, where she visits the prestigious Villa Cimbrone and samples the authentic cuisine of Ravello's celebrity cook, Mamma Agata.

Alex continues her journey, arriving in central Italy where she uncovers the secrets of the undiscovered Le Marche region. Here, Alex discovers a local seafood delicacy and unleashes the credit card with the designer of one of Italy's leading shoe brands. From Le Marche, Alex crosses the country to the capital, Rome, one of the greatest cities on Earth and a place that she knows well. It's an opportunity to take a trip down memory lane, meeting ex-boyfriend Luca, and it's the perfect prelude to a visit to the hillside village of Monforte, her late grandfather's home.

The first leg of Alex's journey takes in some of the secrets that the North of Italy conceals. Venice is a city that Alex has been to at least 40 times, but this is a trip like never before, visiting a prison with a difference and a brush with some memories of her grandmother. From Venice, Alex will spend time in a hidden gem nestled among the Lombard Alps, before rounding up her northern adventure in achingly cool Milan, Italy's fashion capital and the place where Alex gets up close and personal with Maria Callas' fabulous stage costumes.
