Kessler is the exciting sequel to the classic BBC drama series Secret Army, and sees Clifford Rose reprise the role of Ludwig Kessler - a part for which he won much critical acclaim. Written by Secret Army's script editor and principal scriptwriter, John Brason (Enemy at the Door, The Fourth Arm) and its creator Gerard Glaister (Colditz, The Brothers, Howards' Way), this six-part thriller takes up Kessler's story some thirty years after the war. The investigation of Belgian journalist Hugo van Eyck into the true identity of the successful German industrialist, Manfred Dorf, brings Monique Durnford (Angela Richards) back to Brussels for a reunion with her Lifeline colleagues, Albert Foiret (Bernard Hepton) and Natalie Chantrens (Juliet Hammond-Hill). Other new arrivals to the Belgian capital are West German Intelligence agent Richard Bauer (Alan Dobie - War and Peace, Cribb) who fears the re-emergence of National Socialism, and army-trained Israeli Mical Rak (Nitza Saul - Doctor Who) who is seeking revenge for her dead mother. Kessler's colleagues in the Kameradenwerk decide that he must leave Germany behind, and he heads to London with his determined daughter Ingrid (Alison Glennie - Blake's 7) and his manservant Franz Hoss (Nicholas Young - The Tomorrow People). However, the persistence of Kessler's pursuers ultimately forces him to leave Europe for Paraguay. There he is reacquainted with his old friend Don Julian Yqueras (Guy Rolfe - The Secret Army) and the despised Dr Josef Mengele (Oscar Quitak - The Death of Adolf Hitler). Kessler holds the key to the global future of Nazism and seeks an audience with Reichsleiter Martin Bormann. Will Hans Ruckert (Ralph Michael - Empire of the Sun) and the Kameradenwerk or Ingrid's Neo-Nazi organisation gain access to the legendary Nazi fortune? And what role will Kessler take in the Fourth Reich?
