Recruit Mickey undertakes the toughest and most dangerous military training course known to man: SAS selection. The UK's Special Air Service (SAS) is tasked with covert and overt missions in some of the most dangerous places in the world. We follow Mickey through every gruelling stage of selection that not only smashes him physically but also mentally. But when the Counter Terrorism Squad is given charge of a highly explosive siege in London, Mickey must show that he really does have what it takes to be a special-forces operative.

Many try. Only the elite prevail.
