Following the adventures of a bunch of nobodies who get up to a whole lot of nothing in the fictional prairie town of Dog River, Saskatchewan, Corner Gas focuses on the life (or lack thereof) of Brent LeRoy, proprietor of a gas station that is the only stop for miles around and a hub of action on the Prairies.

In 1921, friends and train porters Junior and Zeke find their unbreakable bond stretched to its limits when tragedy inspires them to take conflicting paths to a better life.
