Megan Williams is eighteen and in love with the boy next door, Victor Evans. It is 1910 and, in the Rhondda Valley, poverty and hardship are taking their toll as troops are brought in to control the striking miners. The only work Megan can find is in a house where the police and soldiers lodge, but she is shunned by friends and neighbours, who believe she has betrayed her class by working for the enemy. Megan's father would rather see his daughter dead than married to a Catholic, particularly one whose father and brother are marked as strike ringleaders. Caught in the middle, Victor and Megan find themselves fighting for the right to love one another, remain together and build a future they can share.
