I fix things. I can build you a house or remodel your bathroom. I can also make bad situations - and bad people - disappear.' Meet Mike. Runs a building site, drives a ute, likes a beer, loves his nail-gun. But Mike is hiding in plain sight. When the Pentagon call him in as 'Big Unit', he's another kind of contractor - one as handy with a Colt M4 as he is with a Skilsaw, a man as accustomed to danger, death, and pain as he is to a hammer and nails. In six action-packed true stories we follow a man who left foreign intelligence for a life 'on the tools', only to discover there's too many dangerous scenarios and terrible people still out there. The good guys need a James Bond in Blundstones. They need The Contractor Tradie. Spy. Big Unit. Follow Big Unit as he goes undercover to save a family trapped by an ISIS-run drug cartel in the seedy back streets of Northern Pakistan to terrorist-besieged Paris to a deadly game of cat-and-mouse with Australia's most wanted murderer.
