Tasha (Katie Blake) is a textile design student, doing work experience at Mackintosh. She's a posh girl from a leafy suburb and she doesn't fit in. She desperately wants to but she comes from another world. Mack (Philip Glenister) is feeling his age. Living alone in his suburban family house, his dissatisfaction with life is growing. This is not what he wants, surrounded by housewives driving 4 by 4s, spending his weekends at elderly neighbour's barbecues. There's got to be something more.

They're not shocked, but it highlights the differences - they don't live the life where people can afford to snort coke. Just another thing that marks her out.

Jenny (Sophie Okonedo) has a pretty good life. She drives a forklift at Mackintosh alongside her best mate, Suzie (Nicola Stephenson), so work is a real laugh.

It's the day after Jenny's hen night. Nursing a whopping hangover, she's not feeling much like fork lifting, but she's still happy as anything. Until she glances at one of the heating contractors (Sean Gallagher), working on Mackintosh's cooling system. There's a jolt of recognition and her face contorts. Whoever he is, this man has put the fear of god into her. Nauseous, she runs to the toilets, but not before he has clocked her too. Jenny tries to carry on as normal, avoiding him. B

Suzie Davidson is getting married to Jamie, the man of her dreams, but she disappears through the bathroom window in her wedding dress, leaving him at the altar. She later confesses that she has slept with bad boy old flame Stuart, and no-one at the factory seems to be in the mood to forgive her. And the strain she's put on her father suddenly takes its toll.
