When three armed intruders broke into  "Michael"'s Melbourne home in the dead of night, they weren't expecting a fight. Armed with machetes and a gun, the men ransacked his home demanding money. What they got instead was a man who refused to back down.

Bloodied but unbeaten, "Michael" held his ground using nothing but a decades-old ornamental sword and the muscle memory of martial arts training he hadn't used in 20 years. No one has been arrested. And "Michael" suspects someone he trusted set him up.

Adam Shand sits down with "Michael" inside the home where it happened — carpets ripped up, locks still being changed — to hear a raw, first-hand account of survival, betrayal and a justice system that's yet to deliver answers.
