Robert considers marriage to the wealthy and independent Shirley Keeldar to solve his financial woes, yet his heart lies with his cousin Caroline, who, bored and desperate, lives as a dependent in her uncle's home with no prospect of a career. Shirley, meanwhile, is in love with Robert's brother, an impoverished tutor - a match opposed by her family. As industrial unrest builds to a potentially fatal pitch, can the four be reconciled?
