[1] Written by Zonder and Omri Shenhar and directed by Daniel Syrkin,[2] the series premiered in Israel on 22 June 2020[3] and 25 September internationally on Apple TV+.

Featuring dialogue in Hebrew, Persian and English, the series follows an Iranian-Jewish Mossad agent on her first mission in Iran's capital Tehran, which is also the place of her birth.

[9] On 8 February 2023, it was announced that the series had been renewed by Apple TV+ for a third season, with Hugh Laurie joining the cast.

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.

[11] When she arrives in Iran, she switches identities with Zhila Gorbanifar, a Muslim employee of the local electric company.

Then she tries to cut electric power to the Iranian radar system, to facilitate an ongoing Israeli Air Force attack.

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.

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.

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.

[24] On 10 September 2020, it was announced that co-creator Moshe Zonder had signed a multi-year "first look" deal to create projects for Apple TV+.

[28] On 28 February 2023, Apple TV+ announced that Tehran had been renewed for a third season, with Hugh Laurie set to join the ensemble cast.

[14] The show's producers and Kan 11 reached an interim agreement to allow production of the third season to continue during the 2023 SAG-AFTRA strike.

[29] The third season, produced by both Apple TV+ and KAN 11, wrapped shooting in Greece in the summer of 2023 and was supposed to premiere around April 2024, but the release was delayed due to the Israel–Hamas war and the ensuing Iran–Israel conflict.

[13][30] Kan announced in April 2024 that they would attempt to persuade Apple to reconsider and approve an alternative release date.

In November 2023, producers were asked to rewrite parts of the fourth season due to real-life events from the war resembling scenes in the series, leading to a delay in the filming and production schedules.

The site's critical consensus reads, "Tehran's expertly plotted twists further elevate a geopolitical thriller deftly balanced between the global and the personal.
