Grime and Punishment: Dirty Britain

Episode 3 (2x3)

:

Internet entrepreneur Martin and his partner in grime Glenn hear about a huge fly-tipping operation blighting a remote Hampshire beauty spot, and raise a small army of volunteers who roll up their sleeves to sort it themselves. Meanwhile, the UK's network of motorways and A-roads rely upon a system of lay-bys to help keep drivers safe, but these safe pull-in zones also attract an unsightly collection of filthy behaviour, and it falls to Huntingdon lay-by warriors Clive and Steve to take on the speeding traffic, atrocious weather, drunk drivers - and those people who confuse lay-bys with lavatories.
