"Leslie Purdon lives and breathes trucking" - "Truck and Driver". It's the 1970s. Trucker Dennis Richardson (Rich) revels in the laughs and camaraderie of his life on the road. He sets up a transport company, North Kent, with two pals. Benny is the one with the short fuse; Rich tries to calm him down - when he's not winding him up. The irrepressible Chuckles has his own way of dealing with tachographs and then there's the indispensable Jean, the rock on which they rest. The determined team go through humorous, and sometimes extreme, exploits as they strive to stay afloat. They run legal when they can and cut corners when necessary, gambling on the new Scandinavian trucks that are changing the industry. They are cheated out of their earnings - but still come up smiling.
