In 1879 London, we are introduced to the rich upper middle class Forsyte family. The nominal head of the family is Jolyon Forsyte, the eldest of several brothers and sisters, referred to as 'Old' Jolyon to differentiate him from his son who is referred to as 'Young' Jolyon. Unlike his cousin Soames Forsyte, who is a solicitor and whose future seems assured, Young Jolyon is a painter and looked upon somewhat askance. He is married to Frances and has a daughter June, but is also having an affair with his daughter's German nanny, Helene Hilmer, who he would like to marry. Meanwhile, his cousin Winifred, Soames' sister, is to be married to Montague Dartie. Rumors and scuttlebutt about Young Jolyon abound, however.
