Season 1

Protagonist Tamar Rabinyan, a young Jewish woman born in Iran but raised in Israel, is a Mossad agent and computer hacker on an undercover mission in the Iranian capital to disable a nuclear reactor.^[1] Her objective is to take down the Iranian air defences for long enough to enable the Israeli Air Force to bomb a nuclear plant, and so prevent Iran from obtaining an atomic bomb.^[11] When she arrives in Iran, she switches identities with Zhila Gorbanifar, a Muslim employee of the local electric company. In Zhila's place she enters the electric company station and connects to the computer network. Then she tries to cut electric power to the Iranian radar system, to facilitate an ongoing Israeli Air Force attack. Her mission fails because her boss, who thinks she is Zhila, tries to rape her and is killed in the ensuing struggle. After escaping, Tamar goes into hiding. Being born in Iran and having moved to Israel when she was six, Tamar now discovers her local roots, goes to see her aunt, and befriends Iranian pro-democracy activists.^[3] Meanwhile, she is hunted by Faraz Kamali, head of investigations of the Revolutionary Guards.

Season 2

Prior to being smuggled out of Iran to start a new life in Canada, Tamar accepts a mission to rescue one of the Israeli pilots captured after the failed reactor mission. At the hospital where the pilot is being held, she encounters Marjan Montazami, a British psychotherapist and local agent for Mossad, who aids in her escape. Tamar's aunt is executed for assisting her, and a devastated Tamar agrees to stay in Tehran with Milad to undertake a new mission: the assassination of Qasem Mohammadi, who has been promoted to head of the Revolutionary Guards. Tamar works to gain access to Mohammadi by getting close to his son, Peyman. Faraz Kamali continues his relentless pursuit of Tamar, but finds himself compromised as Marjan begins working as a psychotherapist for his wife following her abduction and release by Mossad. In spite of Faraz's reluctant assistance, Tamar's attempt to poison Mohammadi fails, as does an attempt to kill him with a booby-trapped phone. Mossad Director Yulia Magen calls off the mission, but Tamar and Milad try to take control of Mohammadi's sports car as he races against his son, which only results in Peyman's death. Marjan is poisoned by Nahid, Faraz's wife. Tamar manages to kill Mohammadi with the explosive mobile phone. Milad is killed by a car bomb planted by Mossad in the escape car, leaving Tamar alone and trapped in Iran with no-one to trust.
