In the first of three programmes revealing the extreme side of Russia, Reggie Yates visits Moscow to get up close and personal with some of the country's far right nationalists.

Russia is the largest country on earth and home to nearly 150 million people. Vladimir Putin is well into his third term as president and, with the west imposing tough sanctions, relations are now the frostiest since the Cold War.

Reggie Yates gets up close and personal with three very different communities in contemporary Russia. By living with them for a week, he explores what it's like for young people living here, 24 years after the fall of the Soviet Union.

In the first of three programmes revealing the extreme side of Russia, Reggie travels to Moscow to meet some of the country's most dangerous people - the nationalists. With Putin flexing his muscles and squaring up to the west, Reggie arrives in the Russian capital only days before a march in which thousands of ultra-nationalists take to the streets in a show of strength and unity. Reggie immerses himself into a world where patriotism and loving your country is becoming the norm, one with very dangerous consequences.

He trains with knife-wielding far right nationalists, talks to the young artists who idolise Putin, and confronts teenage neo-Nazis who believe that if you're not white then you have no place in Russia. Reggie also meets the non-Russians who live in fear of persecution and hears horrific stories of those who have survived vicious racist attacks.

And with the rise of the far right not just in Russia but across many other western countries, including the UK, Reggie asks if this is what can happen when you love your country too much.
