Mosab Hassan Yousef is a son of one of the founding fathers of the Palestinian group Hamas. He grew up in the shadow of Israel's occupation and the shadow of his fathers fight and rhetoric. He was the heir apparent and decided to take up the armed struggle. This got him arrested and in the grips of the Israelis.

He was then interrogated by the Shin Bet (Israeli Security Service) and they tried to turn him, he was still sent to prison. He then ended up working for the Shin Bet and this is his story. Now this is a basic documentary with interviews to camera from Mosab and Gonen Ben Yitzhak (his handler) for the most part. There is also use of archive footage to flesh out the tale and a bit of re-enactment too.

This is actually a very moving and extraordinary film in places with unexpected turns and reveals for both Israel and Palestine. This has the potential to be very divisive as it is a subject that burns close to a lot of people's hearts. That said it is better to discuss than to not and if this film encourages debate then I think that can only be a good thing - as indeed this documentary is too - recommended to those with an interest in modern and World history.
