All four episodes of the Channel 4 drama mini-series starring Claire Foy and Christian Cooke. Written and directed by Peter Kosminsky, the series follows London teenager Erin (Foy) as she travels to modern-day Israel to retrace the steps of her grandfather Len (Christian Cooke), who as a young man was part of the post-WWII British peace-keeping force in what was then Palestine. As she reads Len's diary, Erin uncovers some disturbing truths about Len's time in Palestine, which is played out in a sequence of flashbacks throughout the drama.
