It is said that drug addicts make poor parents. How do a young couple, both of whom are addicts, cope with attending to the needs of their small baby? How does one begin to take drugs in the first place? Should a drug addict marry? The harsh realism of these two episodes owes a great deal to the painstaking, and often painful, research done by the producer, director, and scriptwriter in the twilight world of London's drug addicts – a world where people are middle-aged at 20 and dead by 30. Guest stars Tom Chadbon, Moray Watson, Frances White, David Hargreaves and Edward Kelsey.
