In Donegal in the spring of 1945, a farmhand runs into a burning barn and does not come out alive. The farm's owner, Barnabas Kane, can only look on as his friend dies and all 43 of his cattle are destroyed in the blaze. Following the disaster, the bull-headed and proudly self-sufficient Barnabas is forced to reach out to the community for assistance.

But resentment simmers over the farmhand's death, and Barnabas and his family begin to believe their efforts at recovery are being sabotaged. Barnabas is determined to hold firm. Yet his teenage son struggles under the weight of a terrible secret, and his wife is suffocated by the uncertainty surrounding their future. As Barnabas fights ever harder for what is rightfully his, his loved ones are drawn ever closer to a fate that should never have been theirs.
