Lip Service

After a loved-up month in South America, Cat and Sam arrive back in Glasgow. Having run away from her affair with Frankie, how will Cat deal with seeing her again? Tess has it all - new job, pad and girlfriend - but her first day at work and the arrival of a new flatmate throws up some surprises.

It's Cat's birthday and Sam has planned the perfect day, but Cat feels like a total fraud because she's still sleeping with Frankie, who offers her a very different sort of present. When Tess leaves work early, events take an unexpected turn.

Still reeling, the friends each try to deal with events in their own way. When Sam starts asking questions, Frankie makes a drastic decision. Sadie and Lexy both have surprising guests. Tess enlists Ed's help with the difficult Nora, but is unprepared for the consequences.

Tess and Lexy are getting closer and when Tess goes on a blind date she calls on Lexy for help. Sadie's irreverent take on waitressing gets her into hot water, but Lauren proves helpful in ways she didn't expect. Sam warms to Lexy, but then makes an alarming discovery.

When Sam makes an unexpected visit to the flat, a wedge is driven between her and her friends. The situation with Lexy's stalker intensifies but luckily Tess is on hand to help, although Hugh proves an obstacle. Sadie's relationship with Lauren heats up.

On the day of her first performance, Tess has high hopes for her and Lexy, but things go far from smoothly at the theatre. Sam is also under pressure to lead a major drugs bust, but Ryder is sure she's not ready - is he right? Sadie's weakness for temptation leads her into hot water.
