I've seen lots of articles in the Arabic press trying to dissuade Gazans from being "collaborators" with Israel, but this production brings it to a whole new level.
This propaganda took some time and money to make, and indicates that Hamas is very nervous about Israeli intelligence.
At the end, the alleged spies all describe how relieved they are that they are in jail rather than at the mercy of their Israeli handlers.
UPDATE: David G provides invaluable background here and here.
UPDATE 2: Hamas sentenced a "collaborator" to death yesterday, and sentenced his wife to 10 years in prison.
