Season 4, Episode 7:
When a camera and film belonging to a man murdered in 1987, are discovered in the toilets of a Soho pub, the team enters the glamorous but murky world of modelling to reinvestigate the young man's killing. When the film is tested and processed, the team discovers two images that stand out from the standard christening and wedding shots - a junkie shooting up and shot of a couple kissing. But it is not the images found on the film that raises eyebrows, it is the traces of sperm. Gerry Standing's daughter Emily joins the team when she turns to Sandra Pullman, rather than her father, to help her fulfil her professional ambition. Apart from feeling snubbed, Standing isn't convinced that Pullman is the right role model for Emily as he doesn't want to see his daughter sacrifice her personal life for the job. Meanwhile, Brian Lane starts to unravel emotionally and psychologically. Even by his normally eccentric standards, Lane's behaviour and fragile state of mind is alarming.
