The Tube

Overnight (1x6)

:

Every night, 10,000 workers descend on the Tube to maintain, repair and clean it. We follow this invisible overnight army as they work against the clock in the four-hour window when the power is off. From hard-working Bulgarian cleaner Vladimir, who is amazed that the British government pays for people not to work, to 23-year-old Harry leading his gang of fluffers picking fibres and lint from the tracks. Meanwhile pest controller Mick is called to a smelly problem at Hounslow Central, while emergency response worker Roy gets inside one of the Underground's disused ghost stations, Down Street.
