In 1978 at Pentridge Prison's yard, Keithy George warns Mark not to cross the Painters and Dockers' territory line. The next day Mark breaches the line and stabs Keithy multiple times, escalating the turf war within the prison.

Following the stabbing, the Painters and Dockers place a $10,000 contract on Mark, signaling a deadly warning he won’t back down. The threat heightens the rivalry inside the prison walls as each side prepares for more confrontation. Mark begins to rally potential allies to resist them.

Mark conscripts Bluey Barnes and Jimmy Loughnan to help him lead a siege against the Painters and Dockers. The plan targets the gang's control within the prison environment, showing Mark's willingness to escalate violence. The recruitment occurs soon after the contract is declared.

To get out of the doomed mission, Jimmy shanks Mark and slashes his own arm to claim self-defense. The act alters the dynamic between the men and stalls the planned assault momentarily. The self-harm incident occurs inside the prison.

Mark recovers from the attack and is returned to a separate cell away from Bluey and Jimmy. The separation dampens the immediate internal alliance, forcing Mark to operate more alone. The events occur within Pentridge Prison.

It is revealed that Mark is serving a 16 1/2 year sentence for the attempted abduction of a judge to secure freedom for Jimmy. This background explains his ruthless approach and the severity of his imprisonment. The revelation underscores the stakes of his actions inside the prison walls.

Mark meets with the prison board to request a transfer for security concerns, but they decline. In response, he has his ears cut off in an act intended to relocate him to a mental health wing for the remainder of his sentence. The incident marks one of the darkest moments in his prison experience.

After serving part of his sentence, Mark is released and reunites with his old girlfriend Tanya. They reconnect and attempt to rebuild their relationship in the Melbourne nightlife setting. The reunion sets the stage for subsequent volatile encounters.

Out at a club, Mark's jealousy erupts and he fires several shots with a handgun, creating a brutal scene. The violence signals a rapid descent into lawless retaliation as Mark loses control. The incident takes place in Melbourne's club scene shortly after his release.

Back at Tanya's house, Mark finds her on the phone with Neville Bartos and violently abuses both Tanya and her mother. The brutality exposes the toxic personal environment surrounding Mark. The location is Tanya's home in Melbourne.

Mark goes to Neville Bartos's residence after Neville refuses to lend him money and shoots him in the abdomen. The act confirms Mark's willingness to use violence for money and power. The event occurs at Neville Bartos's home in Melbourne.

Mark visits Jimmy Loughnan at his apartment and reveals he is now working for the police, claiming a green light to shoot criminals. He asserts that Jimmy was supposed to take on the contract and that he heard about them, then pins a confrontation on Jimmy. The tense exchange ends with Mark apologizing and giving money to Jimmy.

In the Bojangles car park, Sammy the Turk tries to lure Mark into something; Mark pulls a sawed-off shotgun and shoots Sammy in the eye after a brief argument. Mandy witnesses the murder from behind a parked car, and the grim scene confirms the violence spiraling from the underworld ties.

Mandy turns crown witness against Mark for the murder of Sammy the Turk. It is revealed that Sammy had led Mark to the car park to cash in on the contract, but he was taken to the wrong car park. The revelation catalyzes legal peril for Mark.

Mark escapes the murder charge but is convicted of malicious wounding of Neville Bartos and sentenced to five years. The verdict caps off a career of violence with a long prison term still ahead. The trial occurs in a Melbourne court.
