Four policemen have shot down Albert Thoulouse's daughter by accident but are acquitted of all charges. Such injustice infuriates the unfortunate father, who abruptly turns from Jekyll to Hyde. Without giving them a second chance, Albert executes two of the men and swears that he will go to the end of his "mission". But, being reported as suspect N°1, he cannot go back to his home. One night he gets to know Claire, a young movie usherette, who accepts to accommodate and help him.

Frackman tells the story of accidental activist Dayne Pratzky and his struggle against international gas companies. Australia will soon become the world's biggest gas exporter as more than 30,000 'fracked' wells are sunk in the state of Queensland where Dayne lives. He and his neighbours have unwittingly become the centre of a massive industrial landscape and they have no legal right to stop mining on their land. Dayne embarks on a journey that transforms him from conservative pig-shooter to sophisticated global activist as the Frackman. He meets the people drawn into a battle that is crossing the ideological divide, bringing together a peculiar alliance of farmers, activists and political conservatives. Along the way Dayne encounters love, tragedy and triumph.
