In a picturesque Welsh village during World War I, the calm of rural life is interrupted when two British cartographers arrive to measure the elevation of a local mound. The proud inhabitants, who cherish their small hill, are shaken to discover that, according to the cartographers' measurements, their mound is nothing more than a hill, putting their pride and identity as a "mountainous" village in serious jeopardy.
The charismatic village leader, a shepherd with an indomitable spirit, decides to take action. With the help of his neighbors, they embark on a mission to add the missing centimeters to the mound, no matter the cost. Amid this absurd yet endearing conspiracy, romantic encounters, rivalries, and, above all, a deep sense of community unfold. As the cartographers find themselves entranced by the village's charming yet peculiar way of life, one of them begins to question whether the reality of elevation truly matters more than the sense of belonging and pride that the people feel for their home.
Through a blend of humor and tenderness, the story invites us to explore themes such as identity, cultural pride, and the importance of small things. In a world where war looms on the horizon, the bonds that unite the community become a refuge, demonstrating that sometimes, true elevation is measured in the heart rather than in feet.
