In the final episode Nick reaches Argentina, the land of gauchos, Evita, passion, and, surprisingly, Welsh people. Nick first attempts to master Argentina's most beloved sport, polo. Here the highly skilled horseback game is not just the preserve of royalty but is the obsession of the entire nation. It's a white-knuckle ride, but Nick gives it his best shot.

On the banks of the vast Parana River Nick meets Maria, a woman on a mission to empower other women to pierce the heavily male dominated fishing industry. She created a cooperative employing fisherwomen, increased the price of fish locally, and she doesn't hold back on her critique of Nick's fish filleting skills.

Nick drives through sparse, open grasslands known as the pampas to a cattle ranch which is home to a jaw dropping 3.75 million dollars' worth of beef. He relishes the opportunity to jump on a quad bike and join the gauchos moving the cattle to fresh pasture.

In rural Argentinian Patagonia, Nick finds a Welsh enclave. He meets a descendent of one of the 153 migrants who moved to Argentina in 1865 to set up a Welsh community away from the oppression of the English Government. Wales and Argentina both share a passion for rugby, and Nick is invited to join a training session with Argentina's first mixed ability (disabled and non-disabled) rugby team. Each player is treated equally and as Nick soon discovers - they take no prisoners!

In the capital, Buenos Aires, Nick meets writer Claudio Soria who sheds some light on Argentina's most divisive celebrity, Eva Peron. They meet at the cemetery where Evita's grave is marked, and Nick is staggered to learn that her body was abducted by the military and hidden for nearly 20 years before eventually being laid to rest here.

Finally, Nick enjoys a mouth-watering experience at one of the best steak restaurants in the entire world, Argentine beef at its finest. And he embraces the passion of Argentina, when he's taught the Argentine tango, the fiery and iconic dance that came from humble beginnings – and was originally danced by pairs of men.

South America has been a thrilling, jaw-droppingly beautiful adventure and Nick is sad to say goodbye.
