In the small Cornwall port, fishermen and harbour authorities enforce the three-mile limit that fuels frequent spats with their Breton rivals. Nat Pomeroy, the Cornwall harbour-master, confronts Lanec Florrie when tensions flare. Beneath the surface there is a growing mutual respect between the two communities that hints at a different future.

Sue Pomeroy has been friends with Bob Tremayne since childhood, and their eventual marriage is seen as typical for the town. The looming rivalry adds pressure to their relationship, though their bond remains strong. The possibility of crossing cultural lines begins to feel both risky and inevitable.

During a Cornish visit to Brittany, Bob and Yan headline a wrestling match that raises tempers and leaves Yan with a broken bone. Yan's attraction to Sue becomes more apparent as the match ends in his favor. The crowds cheer on, yet the incident intensifies the rift between communities.

Sue is torn between her long-standing love for Bob and Yan's growing devotion. The rivalry between Cornish and Breton factions feeds the tension, even as hearts turn toward romance. The possibility of a cross-cultural marriage begins to feel closer to reality.

As war-related danger rises, both communities realize they must unite against a common German enemy. Old feuds recede in the face of looming invasion and the need for mutual support. The idea of shared purpose begins to drive actions more than disputes.

With the outbreak of hostilities looming, Bob Tremayne is called up to join the Royal Navy. He prepares to leave, aware that Sue's future may be decided in his absence. The war's shadow makes every moment more charged.

Before Bob departs, he confronts Yan in a defining conversation about Sue's choice. Yan affirms his own feelings and promises to respect Sue's decision. The two men agree that Sue must be allowed to follow her heart.

Yan travels to Cornwall to take up war duties, becoming part of the Breton presence on the coast. He and Sue continue to navigate their complicated feelings in a shared port.

With many men away at war, a loose sea mine drifts into the harbour and threatens the town. Lanec Florrie bravely mans a ship to net it and tow it out, earning hero-status and easing communal tensions. Her actions symbolize cooperation over rivalry.

Encouraged by her wartime heroism and desire for unity, Lanec pushes Sue and Yan to marry. They choose to wed without Nat Pomeroy's consent, a bold act that reflects the new bond between communities.

Sue and Yan marry despite the harbour-master's disapproval, cementing a personal alliance that mirrors the broader coming-together of Cornwall and Brittany. Their union stands as a quiet victory against old feuds. The town begins to regroup around shared purpose.

As the war endures, the communities carry on with renewed unity against the German threat. The Cornish harbor and its Breton neighbors find common ground in practical work and mutual respect. The film closes on a note of tentative peace built on collaboration.
