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 try to recover over £11,000 from a cleaning business that owes money to an ex-employee after an employment tribunal ruled that she had been dismissed unfairly. Vlad is tasked with retrieving a debt of over six grand from a catering and party planning business, and Lewis attends the address of a debtor who has not kept up on repayments on her debt of over £4000.

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.

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.
