Company director William Reeve goes undercover on the shop floor of multi million pound gaming business Paddy Power and unearths some shocking problems behind the scenes

Former celebrity hairdresser Jacqui McIntosh, now a senior manager of The Francesco Group, is on a mission to find out why the company's profits are down

Pam Finnis, managing director of one of Britain's biggest care home firms, goes undercover to investigate standards of care. The private care home industry has been plagued with problems. In 2011, scandal-hit Southern Cross - then Britain's biggest care home operator - collapsed under £50 million of debt. HC-One stepped in and took over a third of the homes. They now care for more than 10,000 people across 241 UK care homes, and the woman in charge of the day-to-day running of the company is Pam. Ex-nurse Pam finds going back to the floor tougher than she imagined. She discovers one home is in need of urgent refurbishment; she breaks down when she hears how her staff struggle to survive on their low wages; and she's upset to discover overstretched night shift staff unable to respond immediately to residents' calls for help. But Pam's also inspired by dedicated employees, some of whom choose to work on their days off in order to spend more time with residents.

Gunnar Blomdahl, CEO of one of the UK's biggest ferry companies, Stena Line, goes undercover on some of his own fleet of ships to find out if the business is delivering its promise of convenient, efficient and relaxing travel. Stena has recently invested over one billion pounds in increasing the look and size of its operation, but Gunnar is worried that standards have slipped. What he discovers undercover shocks him - paying customers onboard a building site at sea, sub-standard customer service, and flawed design on a brand new superferry. When he meets foreign crew earning less than the UK minimum wage and staff dealing with the uncertainty of seasonal contracts he faces difficult moral questions, and is moved by a Filipino crew member coming to terms with the death of his daughter while working away from his family. When Gunnar returns to head office he's determined to make changes.
