Louise and Kate are twenty-something superbabes who have been best mates since they were kids. They share everything: a flat in the funky part of Manchester; a market stall where they sell handmade jewellery and they are about to share their first man. Louise earns extra cash as a guinea pig in sleep deprivation experiments. This is where she meets Charlie, a cute, dishevelled doctor who is assigned to monitor her. It's not long before they embark on a passionate love affair. But when Kate and Charlie meet for the first time, the attraction between them is electric, and it's not long before Louise starts to get paranoid. When Kate complains that she's short of cash, Charlie suggests that she does a stint at the sleep centre. Sure enough, the two are soon tearing each other's clothes off. Trouble starts when Louise announces she's planning to ask Charlie to move in, and Kate admits she's in love with him. The girls head for the sleep centre to confront Charlie.
