Ben Matthews enlists in the army and ends up serving in Ireland, where there is resistance to British rule. His sister's husband Philip Hargreaves is sentenced to death as a conscientious objector but is given a last-minute reprieve.
During the coal lock-out in 1921, Ben's army unit is redeployed from Ireland to police the dispute in County Durham. Ben deserts the army and is sheltered by a miner named Joel. He begins a relationship with his eldest daughter. When donations of food from Liverpool is intercepted by the police and the army, the miners revolt and take some soldiers hostage. Joel and his comrades then make demands on the pit owner, Mr. Pitchard.
