What compels people to keep large amounts of items that to the outside world are considered worthless and useless - but to them are hugely valuable? Dagenham-based 48-year old William is the first man in Britain to receive an ASBO for hoarding.  For him, hoarding is a full-time occupation - and he's inspired by his childhood heroes, the Wombles, who used to collect rubbish on Wimbledon Common. He believes that Uncle Bulgaria, the Chief Womble, tells him to collect. But William doesn't just collect any old rubbish - he collects his neighbours' rubbish. And every night, under the cover of darkness, he heads out on a stealth mission to forage for goods... But armed with the ASBO, his local council are keeping a close eye on him, and William will face an enforced clearout. Here is when the dark side of hoarding is uncovered and it's truly disturbing. Hoarding affects 1 in three people with OCD which means 300,000 people in Britain have hoarding tendencies. It's something that usually goes on behind closed doors but, in America, hoarders become celebrities.
