TV documentary 2050

In 2010 the Icelandic volcanic eruptions started, they lasted for over two years. The plumes of smoke closed airspace across  Europe, people were stranded, unable to get home. Local communities sprung up away from home for example on this little corner of  Grand Canaria there is a little czech village.  But this is the sad story of one welshman who was stranded in Ukraine
From his appearance with hsi long grey beard and unkempt appearance you would think he has always been a tramp but this man was a up and coming star of the TEFL world.

But this poor man had gone mad well before the end of the eruptions. Since then he has  resisited all  efforts to send him home he wanders the streets of Kiev, shouting I was only meant to be here 5 days, five days.
