In 1942, on the recommendation of 26-year-old Bob Santamaria, Australia's Catholic bishops created a clandestine church organisation to smash the Communist Party's massive trade union base. Soon, The Movement, working closely with ASIO, became a sophisticated intelligence agency that would influence every corner of politics. Santamaria based his Movement (also called The Show) completely on the Communist Party, copying its spectacularly successful union-organising machinery. Within a decade, it had defeated communist power in many major unions. He also adopted the communists' strategy of infiltrating the Labor Party, and embarked on an aggressive program to transform it into a Catholic political machine, helping spark the great Labor Split of the mid-1950s. Ironically, in modelling the Movement on his enemy, Santamaria imported its most odious characteristic: Stalinism. He rapidly embraced the characteristics of a Stalinist leader, actively cultivating his own 'cult of personality'. Over time, this infected The Movement, as it adopted authoritarian practices and imposed anti-democratic policies on the unions it controlled, mirroring the communists' modus operandi . As in the Communist Party, this inevitably caused internal battles and catastrophic splits that undermined and, eventually, destroyed The Movement. Weaving together a rich story from previously secret archives of both The Movement and the Communist Party, ASIO's massive files, and extensive oralhistory interviews, The Show exposes a previously unseen side of Santamaria's Catholic Movement.

In early 1965 at age thirteen, Mark Aarons came under the 'adverse notice' of ASIO, which opened volume one of his nine-volume security file. Mark was following in the footsteps of his father, Laurie Aarons, whose 85-volume file commenced in the early 1930s when he was fourteen. For four generations the Aarons family were 'subversive revolutionaries', avowed communists who challenged the established constitutional order. Having obtained access to his family's ASIO files - the largest collection in the nation's history - Mark Aarons combines their meticulous chronicles with his family's own accounts to tell a political tale of revolution and dissent, idealism and intrigue. It is also an intimate story of life under surveillance, a reflection on communism and its legacy, and on what it was to be a radical in Australia in eventful times.
