It's a convoluted John le Carré spy drama set in 1979 in England, Germany, Lebanon, and Israel. It follows a Mossad supervisor, Martin Kurtz (Michael Shannon), and his agents who are trying to catch a Palestinian master bomb-maker, Khalil (Charif Ghattas). Other team members are Gadi Becker/Joseph (Alexander Skarsgard), Shimon Litvak (Michael Moshonov), Rachel (Simona Brown), and Rose (Kate Sumpter). They co-opt a radical young English actress, Charlie Ross (Florence Pugh), into their plot.
First, the Israeli team pursues Khalil's younger brother, Michel/Salim (Amir Khoury). They set up a complex ruse after capturing Michel, having Charlie pose as Michel's lover in hopes of infiltrating the terrorist organization. In true John le Carré fashion, the story includes considerable ethical ambiguity and questions about everyone's motives and ultimate loyalties.
This mini-series is far superior to the 1984 movie that stars Diane Keaton. The mini-series is much more nuanced, and Florence Pugh is more age-appropriate for Charlie's role. Michael Shannon is also a superior Martin Kurtz character. The mini-series also allowed the development of some key characters like Khalil's sister, Fatmeh (Lubna Azabal). The mini-series does take some liberties that deviate from the book, including a sanitized ending. The 1984 film was more accurate on that score.
I think John le Carré would have approved this series.
