Viscount Glencore has retreated to live alone with his son in Glencore castle after his wife deserted him claiming she did not love him. He wishes to exact revenge on her by denouncing the marriage and therefore proclaiming his son to be illegitimate. This consequently robs the child of his birthright and upon his father telling him his intentions, the boy runs away and refuses to return home. Glencore asks his old friend Upton to become the boys guardian to which he agrees after much protestation against it. The boy and his companion Billy move abroad to pursue their schooling and try to live a life of anonymity but all does not go according to plan. (Summary by Michele Eaton)
