Nine years have passed since the events of the first series. June Forsyte (Gillian Kearney ) takes her half brother Jon on an impromptu visit to her Aunt Hester’s (Ann Bell). She discovers that it is Hester's birthday and a party is being held with other members of the Forsyte family, including Soames and his daughter Fleur. The children are encouraged to play outside, and playing by a pond Fleur soils her dress with mud. Soames shouts at Jon for encouraging bad behaviour. Back at Robin Hill, Irene Forsyte is angry when Jon talks about the "nasty man" that yelled at him, and is disappointed that June should have exposed him to that side of the family. She hopes that he will forget the encounter quickly.
Eleven years later in 1920, June is running a fashionable gallery in London and has a new exhibition. Soames and Fleur visit the gallery, not knowing it is June's, and encounter Irene and Jon there. Irene is instantly made ill at ease with the presence of Soames, but Jon and Fleur seem to be intrigued with one another, especially upon discovering that they are, as Soames puts it, "distant" cousins. Irene is disturbed by the meeting and tells her husband Jolyon that Jon appeared to be "entranced’ by Fleur. He tells her not to worry, that boys of his age are fickle, and that the interest will pass.
Fleur knows that Holly Dartie (Amanda Ryan) is Jon’s half-sister (and that he is currently staying at Val (Julian Ovenden) and Holly’s farm). At her 18th birthday party, she invites herself to stay with them in order to meet Jon again. At the farm, when Jon is introduced to Fleur, she pretends they have not met before. She sneaks off early one morning to find Jon, who is working at the nearby farm of Mr Maple. The two connect immediately, and both wonder what secrets in their family’s past have created the feud between their families. They agree to keep their friendship a secret. However, Holly is becoming aware that something is between them, and confides in her father Jolyon and stepmother Irene, who are worried.
