Rutherford and Son starts with Rutherford's son John turning his back on the glassmaking business and marrying a working-class girl, Mary but eventually returns after realizing he wants to succeed his father.
He sent John to Harrow School to have him educated as a gentleman, but to his disgust John turned his back on the business and went to London, where he married a working-class girl, Mary. When John and Mary had a child, Tony, they could not afford to feed and look after the baby properly, and they have come back to live in Rutherford's house.
