A bunch of lads are driven to seek work in Dusselfdorf, Germany; due to mass unemploment in the UK. Auf Wiedersehen Pet is grimey and social realist in places; it has a strong left political message...but dont think it's serious.
The majority of the series, following the group of misfit brickies and carpenters from Germany to Spain and eventually Cuba, has a lads day out/ brits on holiday feel.
The poverty and depravation in which they are forced to live gives the group a brotherly feel, in it together; one for all and all for one. However most of what they earn ends up spent in pubs and on laddish conquests. The constant conflict with the Germans makes for many a hilarious moment.
I can't really explain why, but the geordie, Manc and Birmingham accents throughout make the whole thing that much more enjoyable...I could listen to Jimmy Nail read the phone book.
Its a fantastic series as a whole..but season one was the best of them all. Just watch one episode and I guarentee you'll be hooked.
