In 2013 London Underground is 150 years old. Following on from BBC2's The Tube series, this programme tells the story of the underground through the eyes of the people who work for it. Farringdon station supervisor Iain MacPherson reveals why his station - the original terminus - was constructed in the 1860s, and recalls the dark days of Kings Cross in the 1980s. Piccadilly line driver Dylan Glenister explains why every Edwardian station on his line has its own unique tiling pattern and how, in the 1930's, the construction of new stations expanded the borders of London. With privileged access to disused stations and rare archive footage, this is the tube's hidden history, revealing why it was first built and how it has shaped London ever since.

Vidal Sassoon is more than just a hairdresser-he's a rock star, an artist, a craftsman who "changed the world with a pair of scissors." With the geometric, Bauhaus-inspired hairdos he pioneered in the 1960s and his "wash and wear" philosophy that liberated generations of women from the tyranny of the salon, Sassoon revolutionized the art of hairstyling and left an indelible mark on popular culture. This documentary traces with visual gusto the life of a self-made man whose passion and perseverance took him from a Jewish orphanage in London to the absolute pinnacle of his craft.
