Inspired by true events, Operation Buffalo shines a spotlight on a controversial time in Australia’s modern history, the 1950s British nuclear testing in outback South Australia.

When Carmen's friends, Molly, Lydia and Yvonne, are attacked by an ASIO operative, they show up at Maralinga hospital and confront Leo about the incident and question how it is that ASIO knew where to find them.
