The aptly named Crapper and Sons run a landfill site in Wiltshire where they oversee the disposal of more than 200 trucks of waste a day. But with space running out and landfill losing favour, the father and son need to find new ways of keeping their rubbish dynasty alive. The film also follows two technicians at a sewage works in west London, who have the unenviable task of removing the wet wipes and other rubbish that gets flushed down people's U-bends, and a team of litter collectors at Marylebone Station.
