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

Now a fully-fledged member, Snoddy does his best to calm bristling egos when Caesar Campbell and his brothers threaten to become a club within a club.

The tensions with Jock’s western chapter make a mockery of club loyalty, Snoddy and the city chapter reject their Comancheros colours to join the Bandidos.

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

Father's Day, 1984. A swap meet at Milperra becomes the moment of truth for both the Bandidos and Comancheros.

The confrontation leaves six bikers and one innocent bystander dead. But the tragedy of Milperra is far from over.
