Thanks to his police officer father's efforts, Shawn Spencer spent his childhood developing a keen eye for detail (and a lasting dislike of his dad). Years later, Shawn's frequent tips to the police lead to him being falsely accused of a crime he solved. Now, Shawn has no choice but to use his abilities to perpetuate his cover story: psychic crime-solving powers, all the while dragging his best friend, his dad, and the police along for the ride.

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.
