It's the Wednesday after Easter weekend 1976 in Melbourne, Australia, and a good chunk of the city spent the weekend at the racetrack. Bookies handled swarms of people placing bets and left with a record breaking payload by the end of the melee. Now counting their winnings at the Victoria Club, they hear a bang, and six men wielding World War 2 era machine guns swarm the bookies and take their entire cash haul of $15 million AUD, making it the largest armed robbery in Australia's history.
