The Disappearance (was on BBC4 all episodes now on iplayer)
 

Started watching this last night it is a French TV series with subtitles in english and is absolutely gripping. One of the best finds i have made for a while.
Well worth a watch.

It is the story of a girl who goes missing after going to a music festival.
