Guy Martin follows in the footsteps of his brother and sister, both of whom were firefighters - "well, I suppose it's in the blood". Before dawn, Guy arrives at Peak's Lane Fire Station in Grimsby – the town's busiest station – to work a full 24-hour shift on Green Watch. As well as joining the crew of Papa 4 on any call outs through the day - "got to drive through Grimsby with the dee-daas going!", Guy mucks in with cooking meals, works out in a gym for the first time in his life and learns why his fellow firefighters joined the service, what motivates them and how they cope with the harder parts of the job.
