Stripped of their old identities, the raw recruits meet for the first time in London on day one. They receive their first briefing from their 'tutors.' With no time to unpack, they are sent on their first mission: a real test used by Mossad, the Israeli Secret Service. They are given just 10 minutes to talk their way into a stranger's flat and be seen by their trainers drinking a glass of water on the balcony. After only 24 hours on the course, the recruits must learn a vital lesson: every spy can break under pressure. Without warning they are abducted from their safe-houses in the middle of the night and interrogated by intelligence professionals. They must stick to their cover names and avoid giving away any details about their real lives.
