Enforcement agents Mark and Sam are tracking down a builder's merchant, which seems to be located on a working farm with donkeys, sheep and even ostriches. Fellow agent Lewis is on the trail of a man who owes thousands in rent to a former landlord. Mark and Sam also head out with their colleague Vlad to chase down two cases involving rather unusual debtors - international airlines.

Agents Mark and Sam have a debt of more than £180,000 to collect from a dentist. He makes an offer to pay off what he owes on a payment plan, but even at two thousand pounds a month it would take him more than seven and a half years. Enforcement agent Lewis is after a payment of a debt for a classic car sold at auction, which the successful bidder wants to return after discovering the costs of repairing it.

High court enforcement agents Mark and Sam chase a builder who owes over £10,000. On arriving at his address, the man is not in, but is on the end of the phone making threats to the agents. Lewis is trying to track down a shop owner who owes over £7,000 and specialist eviction agent Scott is at a residential address that has been broken into.

Alex returns to an address he's visited before, aiming to collect a £35,000 debt, and Mark and Sam are on the trail of a woman who owes more than a year's worth of rent to a previous landlord. Lewis is on an overnight mission to reclaim a butcher's shop where the butcher has had their license to rent the premises revoked.

In West London, Scott and a team, including 10 police officers, are removing squatters from a council-owned building in which they've been living for nearly a year. Over in the West Midlands, Lewis has his sights on squatters in a residential property and when he gains entry the smell and chaos eventually force him out again. It might be empty of people, but it's full of rubbish.

Enforcement agents Sam and Mark follow up a debt involving a man who owes nearly £5000 in unpaid legal fees. In London, Vlad has a writ to recover nearly £35,000 in unpaid rent - but the debtor lives in Dubai.

Lewis has a challenging enforcement in the north of England, removing a former premier league footballer's one-time agent from a house the footballer didn't know he owned, with the assistance of a solicitor who successfully won a court case that the former agent was trespassing, a locksmith, two security professionals and the police. In Essex, Mark and Sam are trying to recover a debt from a man who owes more than £5,000 to a former customer.

In the south east of England, agents Mark and Sam are on the trail of a debtor who owes more than £20,000. In the West Midlands, Lewis is at a high-end used car business, which owes money to a dissatisfied customer.

Mark and Sam are chasing a debt of nearly £7,000 for a car sold with, allegedly, inaccurate mileage. Vlad has to call an airline office to get the money for a passenger's compensation claim. Also, Mark enforces a writ for an unpaid fuel bill, which the debtor believed he was paying off with a monthly payment, but which isn't the case.
