A family saga set in the picturesque harbour town of Aberaeron in West Wales is the setting for this S4C drama. Domestic conflict, secrets and jealousy set against a medical backdrop are major themes.
The opening of Llŷr's new club in the first episode of S4C's Sunday night drama, Teulu, exposed rifts in the Morgan family, and when Llinos catches her brother, Hywel, kissing Manon – the wife of her other brother, Llŷr – things go from bad to worse.
In the next episode on Sunday, 25 January, Llinos tries to tell Llŷr about the kiss, but he doesn't believe her. And since Hywel denies that anything is going on, Llinos has no choice but to lie.
Despite Hywel and Manon's continuing relationship, both brothers try to rekindle the romance in their marriages. However, when Manon, who works as a GP alongside fellow doctor, Hywel, hears Llŷr has put in a second offer on a new home for the couple, the strain begins to tell. She feels she has to tell her husband the truth.
"Manon is a complex character," says Catrin Morgan, the 24 year-old actress who plays Dr Manon. "Although she loves Hywel, she was afraid not to marry Llŷr because he'd have blown his top. The idea of not showing up at the church on her wedding day scared her.
"She's an attention-seeker and constantly feels the need to know she's loved. But she can't live a lie anymore, and the truth comes out."
Manon's declaration is sure to shake the Morgan family to the core, but what's next for the family doctor?
"Goodness knows what will become of Manon. It's as if she's searching for perfection, without thinking about the consequences," says Catrin.
Also in this episode, Eirlys decides she has to come clean, and in doing so, breaks Eric's heart. And on Lydia's sixteenth birthday, Llinos and Danny's relationship deteriorates.
The Morgans are an extremely affluent family, well known in the area, respected and revered by most. Richard and Margaret Morgan are pillars of the community, with Richard a member of the local rotary and fishing club and well–to–do Margaret helping out with local charities. They live in Bryncelyn and have three children, Hywel, Llinos and Llŷr.
Hywel, the eldest, is a doctor, he has moved from London with his wife, Catrin and young son, Owain; Llinos runs a smart pub and restaurant in the town, Pen y Cei with her partner, divorcee Danny; and Llŷr, the youngest son and apple of his mother's eye, still lived at home in the first series and manages a successful caravan park on his parents' land.
In the first episode, Hywel, faced with the sudden death of his father–in–law, is forced to recognise that his wife, Catrin, wants to come home to Aberaeron. Hywel, a successful doctor in London, is initially vehemently against by the idea. Will the golden boy return to rural Wales?
In the first series, the family's happy existence was shattered by the revelation that Hywel's real father is Dr John and not Richard Morgan. More secrets emerged as Hywel, played by Geraint Morgan, had an affair with his colleague and future sister-in-law, Dr Manon.
Following Llŷr and Dr Manon's marriage and Dr John's heart attack at the end of the last series, viewers were left on tenterhooks. It's sure to be a stormy start for the members of the Morgan family as the series returns.
Rhys ap Hywel plays the cuckoo of the family, Llŷr Morgan. The actor, who played Jason in Pobol y Cwm for a number of years, believes that Llŷr knows that his new wife has had a relationship with his brother.
"Llŷr suspects that Manon and Hywel have had a relationship, maybe he even knows they have. But he's a very determined person and Llŷr would never let his big brother get the better of him," he explains.
In real life, Rhys is married to actress Rhian Jones, who plays his on-screen sister Llinos in the drama. And although Rhys enjoys working with his partner, it's not easy arranging childcare!
"I was really excited when I heard I'd be working with Rhian. But as we have four children, when one of us was filming, the other had to look after them," says Rhys, who lives in Llanegwad, Carmarthenshire.
In the new series, Llŷr is about to open a new club at the caravan park he runs on the family land, and he and Manon, played by Catrin Morgan, are planning to move from Bryncelyn to their new home. Llŷr is as happy as larry, but Manon and Hywel are continuing to play with fire and no secret is safe forever.
"More secrets will be revealed in this series," says Rhys. "But I don't want to say too much, you'll have to watch to find out more."
