Alone and adrift after his discharge from the Navy, Anthony Spencer discovers the seductive world of the outlaw bikie and the formidable force that is William Jock Ross - Supreme Commander of the gang Comancheros.

Now a fully-fledged member, Anthony Snoddy Spencer does his best to calm bristling egos when Mario Chopper Cianter, Colin Caesar Campbell and his brothers Gregory (Shadow) and Phillip (Bull) threaten to become a club within a club.

After splitting into two chapters, tensions with Jock's western chapter make a mockery of club loyalty. Snoddy and the city chapter reject their Comanchero colours and join the Bandidos forming the first ever chapter in Australia.

Hostilities between the two clubs intensify with Jock declaring war on the Bandidos. Forcing the Bandidos to retaliate.

Father's Day, 1984. A swap meet at the Viking Tavern in Milperra becomes the moment of truth for both clubs as they square off in preparation of a bloody battle.

The confrontation at Milperra leaves six bikers and one innocent bystander dead (Chopper and Shadow of the Bandidos. Foggy, Leroy, Sparra and Dog of the Comanchero and 14-year-old girl Leanne Walters). Many of the members from both clubs are imprisoned as they await trial. The stresses and guilt are too much to bare for Snoddy, he relinquishes his Presidency to Bull Campbell before hanging himself in his prison cell. 57 Bandidos and Comancheros are handed lengthy sentences for various convictions. Due to serious misdirections to the jury by trial judge Justice Roden, the Court of Appeal quashed the 'murder' convictions and the majority of bikers were released immediately. Jock served a total of five years and three months for his part in the massacre. His time served was the most of anyone involved.
