Underbelly: Killing Kurt

Show Notes

In 1995, the FBI's years-long investigation into the Chinatown crew comes to a head with sweeping indictments and early morning raids. With their criminal empire crumbling, the Calabrese family faces the full weight of the justice system—and begins to turn on itself. This episode tells the harrowing story of what happens when loyalty becomes a liability. Junior faces a 30-year prison sentence. Kurt is offered a deal: serve two years, and his brother, father, and uncle all get reduced sentences. Despite a lifetime of abuse at the hands of his father, Kurt agrees—sacrificing his own freedom for the sake of family.

But even behind bars, Frank “The Breeze” Calabrese Sr. remains in control—cutting financial support to his sons’ families and manipulating Kurt into continuing the family’s illicit business. With a handshake deal and no paperwork to protect his loved ones, Kurt finds himself once again used by the man he trusted least.

As prison walls close in, and brother turns against brother, Kurt reflects on what it truly means to make a deal with the devil—and what’s left when the devil doesn’t keep his end.
