讲述2名被敌人囚禁的以色列士兵被交换回国的故事。（原版的《国土安全》） The series, set in 2008, depicts three Israeli soldiers who were captured seventeen years ago while on a secret mission with their unit in Lebanon. The story begins with their return home after years of negotiations for their freedom. Nimrod Klein and Uri Zach return alive, while the remains of Amiel Ben-Horin come back in a coffin. The series explores the reintegration of Nimrod and Uri into a society which has made them national icons, and into an interrupted family life, while working through the trauma of being held captive and tortured. On a personal level they have to deal with partners who waited or moved on, children who have grown up without them, and parents who have died. They also have to undergo psychiatric evaluations and military debriefings. When a military psychologist finds discrepancies in their stories, an investigation is launched to discover what they are hiding.
