Picture standing in a vault staring at 154 million pounds in cash, and having to walk away from every penny of it because your 7.5-ton getaway truck is already packed to the ceiling with 53 million. The 2006 Securitas Depot robbery in Tonbridge was the largest cash heist in British history, executed by a crew of cage fighters, bouncers, and roofers who breached a national fortress and were defeated only by the physical dimensions of paper money.

This episode traces the heist from the inside man placed through a temp agency, through a planning phase of glued-shut spy cameras, a 115-mph traffic stop, and a crashed yellow Ferrari full of burner phones, to the chillingly precise abduction of the depot manager’s family that made the fortress open its own doors. Then the unraveling: laundry bags of rotting cash, life sentences, a paralyzing gangland shooting, and the 32 million pounds that has never been found.
