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.

A decade ago, curler Chris Cutter disappeared suddenly on the verge of stardom, dropping his curling stones to the bottom of a lake and leaving his fiancée, Julie Foley, at the altar. But when his former coach dies, Cutter returns home for the funeral and attempts to fulfill the man's last wishes. The team is reunited under Cutter's estranged dad, Gordon — himself a former curling star — for a final attempt at glory.
