Having returned home following 17 years as a captive in Lebanon, soldiers Nimrod and Uri quickly found that the world, and their families, had continued without them. As well as battling the emotional turmoil, post-traumatic stress and terrible flashbacks associated with their release, Nimrod and Uri were also forced to fight against the suspicions of military psychologist Haim Cohen, one of many who believed that the two heroes had been turned and were waiting to commit a hostile act against their county.
All the while, Nimrod and Uri tormented themselves, convinced that they were traitors who had given away important information about their country under duress and wracked by the guilt of being responsible for the death of their fellow soldier and prisoner Amiel, who they believe had returned to their home country in an urn.
However, as series two begins, Nimrod and Uri begin to find clues that Amiel didn't die in captivity but is living in Syria as a Muslim. As they, along with Cohen, begin to investigate his true fate, they learn that he was turned by the organisation who subjected him, Nimrod and Uri to 17 years of physical and psychological torture.
