When people disappear, they leave holes in the lives of friends and family that can never be filled. The writer Andrew O'Hagan and the artist Graham Fagen have both created works on this highly emotive subject. O'Hagan's play for the National Theatre of Scotland, The Missing, was adapted from his 1995 book of the same name. Fagen's companion piece - a moving image work called Missing - was commissioned by the Scottish National Portrait Gallery. ArtWorks Scotland followed the making of both the play and the film and revisited, with Andrew O'Hagan, some of the people and places featured in the original book. The programme combines intimate footage from the rehearsal room and research and filming by Graham Fagen with moving testimony from those left behind by the missing.
