Knock, knock - it's a hot summer night and Roger Rogerson is at the front door with a posse of Sydney's toughest cops.
Sticks of gelignite are discovered, and the family's young men are taken off for a rough night at CIB headquarters, joined by others arrested in simultaneous raids across the city. For them, and the entire community of migrants from Croatia, it's the start of a nightmare, ending in 15-year jail terms for terrorist conspiracy.
But even during their 10-month trial, holes appeared in the police case. Later the chief crown witness confessed on TV he made up his crucial testimony.
Decades later, a chance reference drew Walkley Award-winning journalist Hamish McDonald to explore this case. He uncovers evidence that authorities took pains to conceal from the court: that the crown witness was an agent of the Yugoslav secret service and had been under ASIO surveillance.
