An Israeli-produced series debuting on Apple TV Plus, “Tehran” is a show that looks at Iran through an alternately adversarial and nostalgic lens. The protagonist, Mossad agent Tamar Rabinyan (Niv Sultan), infiltrates the nation following an emergency landing of a passenger jet in the capital city; she is on a mission that, should it succeed, will have the long-tail effect of thwarting what the viewer is made to understand are Iran’s nuclear ambitions.
