I Am Soldier follows Mickey Tomlinson (Tom Hughes), a military chef, who attempts the most dangerous military selection known to man: The Special Air Service (S.A.S.) selection. The S.A.S. Is the United Kingdom's most renowned Special Forces Regiment, tasked with life-threatening missions in some of the most dangerous places on the planet. Mickey has more military experience than simply being a chef, something he doesn't let on to the other candidates - Mickey is smashed by this selection process - his mind, body and soul scream for mercy as he endures torturous speed-marches over the steepest mountains, running for his life during 'Escape and Evasion' and then facing the most evil interrogation possible, during the deadly phase known as: 'Tactical Questioning.' Even after everything, there is still only one way you can really prove yourself: in combat - Many try to get into the S.A.S. Only the elite make it.
