A year has passed since the troubled love lives of Katie, Trudi, Jessica and Siobhan left them heartbroken, as the BBC One drama starring Sarah Parish, Sharon Small, Shelley Conn and Orla Brady returns. However, while their friendships are still as strong as ever, their lives have changed a lot…

Having moved on from her first love with lesbian Alex, Jessica has been swept off her feet by playboy Mark, and the ultimate commitment-phobe is getting married. However, her friends discover things are not as straightforward as they thought when Jessica starts kissing a handsome stranger on her hen night.

Meanwhile, Katie’s suspension from practicing medicine has come to an end and she is ready for her first day on the oncology ward, where her new boss is Jack, an old flame from medical school. Katie has sworn off men, but it doesn’t take long before she attracts the attention of Dan, a surgeon at the hospital. Reluctantly, Katie gives in to Dan’s charms and invites him on a strictly platonic date to Jessica’s wedding.

Trudi and Richard’s relationship is still going strong, but money is tight and life is chaotic. Trudi decides to take matters into her own hands and tries to earn some extra cash by making cakes. But Trudi starts to feel there’s something lacking in her relationship, and when Richard suggests they should live together to make their hectic lives easier, her romantic sensibilities are offended.

To those on the outside, Siobhan seems to be living the perfect life with house-husband Hari and daughter Elsa. Even Elsa’s biological dad, Dominic, is settling into a regular family routine. However, Siobhan and Hari’s relationship is far from perfect and Siobhan is hiding a very dark secret…
