Main characters
Katie Roden (Sarah Parish) is a GP who, at the beginning of series 1, is having an affair with John Grey, a terminally ill patient whom she later helps commit physician assisted suicide. After John's death, his son, Sam (Max Brown), discovers evidence of this. Distraught, he confides in Katie, unaware of her role in his father's life and they begin a reluctant relationship as she struggles with her grief and guilt over helping John die. Ultimately, unable to lie any longer, Katie tells Sam, who informs his mother and the authorities resulting in Katie being suspended from work for a year.
Series 2 begins with Katie taking a junior post in a hospital department working alongside an old lover from medical school, Jack Hudson (Steven Brand), now married to Megan (Natasha Little) but still holds a torch for Katie. Katie also meets Jack and Megan's friend, fellow surgeon Dan Tate (Mark Umbers), with whom she strikes up a relationship. All goes well until Jack decides to act on his feelings for Katie and they embark on a brief affair. Katie ends the affair before she is discovered but Dan witnesses a final kiss between the pair and decides to move to Australia to take up a medical post he's been offered. Katie leaves a heartfelt note of apology for Dan, which he reads before asking her to go with him to Australia.
Series 3 introduces Katie's mother Vivienne Roden (Joanna Lumley), with whom Katie has a tense relationship. Vivienne has found a new man and intends on selling the old family home where Katie lived as a child, much to Katie's distaste. Later, Katie discovers that her (now-deceased) father had a mistress during his marriage to Vivienne, and Katie softens toward her mother. Additionally, Katie becomes close with Trudi's partner, Richard, (Patrick Baladi) and the two lean on each other during hard times as well as sharing a kiss. Katie rejects a relationship with Richard, but agrees to counsel him on his marriage; but Richard is killed in a car accident on his way to meet Katie at the railway station. Trudi later discovers the plan and, feeling betrayed (thinking the two were having an affair and that Richard intended to leave her for Katie), ends her friendship with Katie.
Trudi Malloy (Sharon Small) is a 9/11 widow and mother of two, who is convinced her husband, Paul, is still alive. In the first episode, she receives a cheque from a 9/11 bereavement fund worth around £1 million and begins seeing Richard (Patrick Baladi), a single father whose daughter goes to the same school as Trudi's daughters. A woman, Sally, makes contact with Trudi, claiming she was Paul's lover while he was in New York City and that they have a son together. Trudi decides to split the money with Sally in order to provide for the son Paul fathered with her, but is stunned to discover that she was right all along - Paul is alive, and used 9/11 as an excuse to carry out his plan of leaving Trudi for Sally. Trudi informs the authorities and returns the bereavement money.
In series 2, Richard and his daughter, Amy, have moved in with Trudi and her daughters and put his house on the market. Trudi wants them to divorce their partners and get married but Richard is unsure. Trudi also starts selling her home-made cakes at a local deli where Lucas (Sean Francis), the owner, is clearly keen on her. Concerns over Richard's finances lead Trudi to discover his secret - that his wife, who he had claimed had abandoned him and Amy, is in a residential home for patients suffering early-onset Alzheimer's. Horrified, Trudi insists that Richard tells Amy the truth about her mother. Despite her brief fling with Lucas, she and Richard reconcile eventually, settling down to life together as a family.
In series 3, Richard is feeling sidelined as Trudi spends all of her time at her cake business, which now has its own factory and workforce. Whilst he embarks on a friendship and brief affair with Katie, Trudi is flattered by the attentions of an investor in the cake business, Chris (Vincent Regan), and frustrated by what she feels is a lack of support from Richard. She enjoys a one-night stand with Chris but soon comes to regret it and is distraught when Richard is killed in a car accident whilst on his way to meet Katie at the train station, where he intends to talk about Trudi's infidelity.
Jessica Fraser (Shelley Conn) is an event planner who has had a string of lovers including her boss, Simon (Adam Astill), and who doesn't get involved in committed, long-term relationships. In the first episode, she is organizing a wedding for a lesbian couple and strikes up a friendship with one of the brides, Alex (Anna Torv). There's clear chemistry between the pair and Jessica realises that she has feelings for Alex, which later become complicated when she begins to fall in love with her. After seeing the trouble caused by her friend Siobhan's infidelity, Jessica breaks off the relationship, despite Alex's offer to leave her partner for Jessica.
As series 2 begins, Jessica is in an open marriage with a man named Mark with whom she had a whirlwind affair. Jessica believes the marriage is a strong one but is shocked by how jealous she is when she realizes that Mark has been engaged in a long term sexual relationship with his assistant, Carrie, (Preeya Kalidas). Jessica makes her feelings known, and though Mark realises she is unhappy he can't bring himself to be faithful to one woman, causing them to split. Jess discovers that she is pregnant and, to her surprise, can't bring herself to have a termination. Mark tells her they should make a go of things as a family and cease seeing other people.
At the start of series 3 two years later, Jessica has miscarried and Mark has gone bankrupt. He is forced to accept a lowly job in a call centre to provide for his family, but the shame of how far he has fallen causes him to quit and Jessica realises they can't afford IVF treatment so Mark accepts a loan from Siobhan, claiming it is for the IVF but actually using it to invest in business, in a bid to regain his lost wealth. When Jessica finds out, she's furious, causing her friendship with Siobhan and relationship with Mark to unravel.
Siobhan Dillon (Orla Brady) is a successful lawyer. She and her husband, Hari (Raza Jaffrey), have been trying to start a family for some time and Siobhan is weary of his obsession with their fertility issues. She flirts with and eventually has a brief affair with a colleague, Dominic (Adam Rayner). Upon seeing a specialist, Hari discovers that he is infertile, but the doctor suggests IVF treatment. Before this can take place, Siobhan is shocked to discover she is pregnant and realises the baby must be Dominic's. Initially, she lets Hari think that he is the father but eventually admits the affair. Hari is heartbroken but nonetheless (after a brief split) agrees to take Siobhan back and raise the child as their own.
As series 2 begins, Siobhan has had the baby – a little girl, Elsa – and returned to work. Hari has become a stay-at-home dad but has not been able to forgive Siobhan for her infidelity and they are sleeping in separate beds. To satisfy her sexual needs, Siobhan secretly goes out during the night and picks up men in hotel bars for anonymous sex. When Jessica discovers what Siobhan is doing, Siobhan tries to argue that this is different, and more acceptable, than her relationship with Dominic because she is not emotionally involved. Things become complicated when she meets Tom McCormack (Thomas Lockyer), an older businessman who is unsatisfied with their one night stand and begins to pursue Siobhan, showing up at her home and becoming a client at work in a bid to insert himself into her life. Eventually Tom resorts to sending photos of him and Siobhan together to Hari, destroying her marriage. Hari bids an emotional goodbye to Siobhan and baby Elsa, then leaves for good.
Siobhan's romances take a back seat in series 3 as she continues bringing up Elsa as a single mother. When Dominic, with whom Siobhan has remained friends, tells her that he is engaged to a woman he met whilst working in America, Siobhan is initially pleased but clearly still harbours feelings for the father of her child. The two grow closer again but Siobhan is determined not to act on her feelings and ruin the wedding plans. Eventually Dominic tells Siobhan it's her that he wants and that he's called off the wedding, and the pair reconcile.
