Thirty years after the Rose of Nevada fishing boat and its crew vanished without a trace, the vessel inexplicably returns to its old harbour in a small Cornish village, unchanged by time. Drawn by the promise of steady work and escape from hardship, two young men join its new crew.

When the Rose docks once more, the men realise they have slipped back in time. Trapped in the past, they are mistaken for the original crew and burdened with the expectations, fears and unresolved grief of a community desperate for answers, forcing them to confront their identity and fate, and the cost of survival.
